 Posted: Tue Oct 28, 2014 6:16 am Post subject: Q: WiFi Works If Cold Boot, But Not Warm Boot |
 |
|
After "emerge -vDu world", a bunch of (about 70+) packages got updated. And then WiFi stops working if I issue "reboot" command. Oddly enough, when I completely shut down the system and start, WiFi works fine. Here is what happens when it's not working.
| Code: | * Bringing up interface wlo1
* Starting wpa_supplicant on wlo1 ...Successfully initialized wpa_supplicant
Could not set interface wlo1 flags (UP): Input/output error
nl80211: Could not set interface 'wlo1' UP
wlo1: Failed to initialize driver interface
* start-stop-daemon: failed to start `/usr/sbin/wpa_supplicant'
[ !! ]
* ERROR: net.wlo1 failed to start |
I'm not sure what it's complaining about and why it happens only during warm boot. I'd appreciate any suggestions.

| Did you check if that interface wlo1 is there? Or did it get renamed? |

"wlo1" is there whether it's in the working state or not. The name doesn't get changed. Besides, I don't see why its name would ever get changed when I reboot the system but not when I start from the shutdown.

Was sysvinit on of the 70+ packages updated?
Does it make a difference if you use instead of ? |

sysvinit was updated from "sysvinit-2.88-r4" to "sysvinit-2.88-r7", but that was several months ago, so I don't think it was a part of 70+ packages. Also "shutdown -r now" gave me the same result: "Could not set interface wlo1 flags (UP): Input/output error".
If I do "ifconfig wlo1 up" when WiFi is not working, it says "SIOCSIFFLAGS: Input/output error". I wish it shows a little more clues. A complete shutdown always brings up WiFi, but I do need to reboot occasionally, so I'd like to solve the problem once and for all.

What happens if you take down wireless with the computer on and bring it back up?
Did the kernel change? Perhaps the driver changed.
If the driver is a module, what happens if you reboot, take down wireless, unload the module, reload it, and try to bring up wireless? |

When WiFi is working, I can do "/etc/init.d/net.wlo1 restart" with no problem. But once I reboot the system, the same command gives "SIOCSIFFLAGS: Input/output error".
I tried reloading all WiFi related modules (rt2800pci, rt2x00pci, rt2800mmio, rt2x00mmio, rt2800lib, rt2x00lib), but the result was same. Converting modules to built-in didn't solve the problem either.
The kernel did upgrade from 3.14.14 to 3.16.5, but using the old kernel was equally ineffective.
I noticed that the upgrade brought in "sys-kernel/linux-firmware-20140603", "net-wireless/wpa_supplicant-2.2-r1", and "sys-devel/gcc-4.8.3" (among various other things). Would reverting them to previous version be worth a try?

Does a diff of dmesg from the two types of boot provide any clues?
It is a low-level problem, probably not wpa_supplicant or gcc. Maybe the firmware.
You might also try re-seating the card. |

Do you use an initramfs? Have you put the rt2800pci module and it's firmware (rt2860.bin) in the initramfs?
It is relevant to know how the wlo1 is start. Is it from a link you made from net.lo to net.wlo1 in /etc/init.d and add net.wlo1 to the default boot level? Or it is from dhcpcd and wpa_supplicant boot scripts? What is the contain of the file /etc/conf.d/net?
Did you check with the
command if the card is blocked after reboot?
If not blocked after reboot and it's not working, after unload and reload the rt2800pci and module dependencies, can you connect using wpa_supplicant and dhcpcd commands from the terminal?
What does return
More info we have, more possibility of a solution is.

Yes, I do use initramfs, but the problem persists even if I don't. I was under the impression that genkernel takes care of putting all the files necessary, but if not, let me know how to make sure the module and the firmware files are included.

I created a soft link from "net.lo" to "net.wlo1" and put "net.wlo1" in the default level.
| Logicien wrote: | Did you check with the

That was the first thing I checked, and nothing seems to be blocked when WiFi is not working after reboot.
| Code: | 0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

This is what happens when I try to use wpa_supplicant after a reboot.
| Code: | #wpa_passphrase "myssid" "..." > wpa.conf
#wpa_supplicant -iwlo1 -Dnl80211 -cwpa.conf
Successfully initialized wpa_supplicant

That patch is not included in 3.16.7, but even if I include it, it didn't make any difference.

This one is interesting and I suspect something might be up with a build somewhere... It is easy enough to check:
Why do I think this is possible?
In a cold boot scenario (e.g. the card is powered down on shutdown) the init scripts activate the card and get it up and running. On shutdown, something may fail but it does not matter since the card will lose power.
In a warm boot scenario (e.g. the card does not lose power) the init scripts fail as the card has some left over state caused by a failure of the tear down process during shutdown.
Caveats
This assumes the problem is related to broken links caused by your package upgrades and not something wrong elsewhere (such as kernel bug). I believe my statements about what is happening are correct, it is the cause I am unsure about.

When I did "revdep-rebuild", the system rebuilt "x11-libs/pango" (and nothing else), but the problem persisted. I went ahead and did "emerge -v --emptytree world" just for the heck of it but the result was the same.
I'm just about to revert all the newly installed packages, go back to the state when it worked fine, and install packages one by one to narrow down the problem, but putting all the newly installed packages in "/etc/portage/package.mask" seems like a rather tedious process. It would be great if I can somehow magically uninstall all new packages at once.

You can.
emerge -avc <package name you explicitly ordered to be installed>
(and perhaps 'emerge -avc' afterwards) |

FWIW, these are the errors in your dmesg

[This is a rather elementary question]
During the upgrade, "sys-kernel/linux-firmware" was updated from 20131230 to 20140603, but the old version is no longer available in portage, so I'm not able to downgrade. How do I emerge the old version?

can pick up the ebuild here, and install it in a local overlay, though you might have to hunt for the firmware file to go with it if it isn't still in your distfiles |

So, I finally managed to create a local overlay and downgraded linux-firmware from 20141009 to 20131230, but it turned out that the firmware in question (/lib/firmware/rt3290.bin) wasn't changed between those two versions. Thus the problem persists.
I'm already out of options that I can think of, so if you have any suggestions at all, please share. Thank you.

Just to make sure I didn't miss anything obvious, I backed up the whole thing, wiped out the hard disk, and installed Gentoo from scratch. The result was same; WiFi works during cold boot but not during warm boot. WiFi also works when the system wakes up from either suspend or hibernation. Unless I was in a complete delusion (which isn't entirely out of the question, but still), it was working without a problem until I did a world update.

What was your solution to this? I'm experiencing the exact same thing now.

Unfortunately, I still haven't figured it out yet. It's somewhat bearable, because 1) I don't reboot the system very often and 2) when I do need to reboot, I just shutdown completely and press the power button. It's definitely annoying, though.
As a next step, I'm planning to install a different distro (Ubuntu, perhaps) and see if doing so makes any difference. In the mean time, if you find any solution, please share. Thanks.

So, I installed Ubuntu 14.04 (kernel 3.13.0-43) along with Gentoo (kernel 3.16.5), and here is the result.
1) Boot to Ubuntu -> Reboot -> Boot to Ubuntu: WiFi works.
2) Boot to Ubuntu -> Reboot -> Boot to Gentoo: WiFi works.
3) Boot to Gentoo -> Reboot -> Boot to Ubuntu: WiFi doesn't work.
4) Boot to Gentoo -> Reboot -> Boot to Gentoo: WiFi doesn't work.
Looks like if I boot to Gentoo and reboot, WiFi stops working regardless of what boots afterwards. Also, after 3), I get the same "SIOCSIFFLAGS: Input/output error" in Ubuntu.
Ubuntu "config-3.13.0-43-generic":
http://pastebin.com/tsjFANW0
Ubuntu "lsmod":
http://pastebin.com/5X5Z6Dvc
If it's possible at all, I'd like to stick with Gentoo (not that there is anything wrong with Ubuntu), so if you have any suggestions, please share.

This is not .config related but a kernel bug.
Why dont you try a probably fixed source:
https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.16.7.tar.xz
And apply your new upstream maintainer patches:
http://kernel.ubuntu.com/stable/patch-3.16.7-ckt1.xz
http://kernel.ubuntu.com/stable/patch-3.16.7-ckt2.xz
Gentoo | Code: | *gentoo-sources-3.16.5 (09 Oct 2014)
219
220 09 Oct 2014; Mike Pagano <mpagano@gentoo.org> +gentoo-sources-3.16.5.ebuild: |
having a two month old kernel source as latest stable is insane. Gentoo just should never declare as stable a short-term kernel.org source,
MyHumbleOpinion
If your issue persists after patching the kernel sources please file a bug. It might be init,udev system related (I think very unlikely). In your case it is most probably not a .config issue. While Linux kernels having a little minor version are known to be error prone you got to go patching and your issue will solve like magic  |

I finally got around installing kernel 3.16.7 along with a couple of suggested patches, but the problem persisted; I received the exactly same error message ("SIOCSIFFLAGS: Input/output error") when I reboot the system, but not when the system start from completely turned off state.
Inform me where/how to file the issue.
