 |
|
I've been running Gentoo on my pc for over a year with little issue, so decided to try it on aT420 laptop. I seem to be having trouble with iwlwifi, an Intel Centrino N 6205, and NetworkManager.
dmesg:
https://pastebin.com/LwiKdYMA
/usr/src/linux/.config
https://pastebin.com/2tR1p6bM
I have
| Code: | CONFIG_EXTRA_FIRMWARE="iwlwifi-6000g2a-6.ucode regulatory.db regulatory.db.p7s"
CONFIG_IWLWIFI=m
CONFIG_IWLWIFI_LEDS=y
CONFIG_IWLDVM=m
CONFIG_IWLMVM=m
CONFIG_IWLWIFI_OPMODE_MODULAR=y
CONFIG_IWLWIFI_DEBUG=y
CONFIG_IWLWIFI_DEVICE_TRACING=y |
and
| Code: | CONFIG_CFG80211=m
CONFIG_CFG80211_REQUIRE_SIGNED_REGDB=y
CONFIG_CFG80211_USE_KERNEL_REGDB_KEYS=y
CONFIG_CFG80211_DEFAULT_PS=y
CONFIG_CFG80211_CRDA_SUPPORT=y
CONFIG_MAC80211=m
CONFIG_MAC80211_HAS_RC=y
CONFIG_MAC80211_RC_MINSTREL=y
CONFIG_MAC80211_RC_DEFAULT_MINSTREL=y
CONFIG_MAC80211_RC_DEFAULT="minstrel_ht"
CONFIG_MAC80211_LEDS=y
CONFIG_MAC80211_STA_HASH_MAX_SIZE=0 |
set.
After boot all I get is ethernet, no wlan, although does indicate the device is present. I have tried both with and without cfg80211 as a module as the iwlwifi manual suggests and have tried with and without iwlwifi as a module as well, neither .config got wlan working. Also, ethernet only starts manually after .
Any suggestions on how to 1) get wifi working and 2) get NetworkManager working are appreciated.
when I only | Code: | | x86_pkg_temp_thermal |
is listed, but when I first set up the kernel there were iwlwifi, bluetooth, and other moduels listed as well - not sure where they all went but that seems to be a problem.
I also think
| Code: | [ 1.131534] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
[ 1.131537] cfg80211: failed to load regulatory.db
[ 5.138021] cfg80211: exports duplicate symbol __cfg80211_alloc_event_skb (owned by kernel)

[ 5.313740] cfg80211: exports duplicate symbol __cfg80211_alloc_event_skb (owned by kernel) |
is part of the problem but am unsure how to resolve it. Also, this system is CoreBooted with SEABios.
Enabled bbcode, given that it was being used. -- desultory |

I suspect this means that cfg80211 is built in AND a module (possible since I've alternated both build on this system), but I thought I had run
| Code: | | make clean && make modules_install |
Does anyone who knows a little more about kernel building want to point me in the right direction to make this kernel clean? |

brb78,
You are not runnig the kernel you think you are.
You made the kernel with __cfg80211_alloc_event_skb built into the kernel. (owned by kernel)
Then you remade the kernel with __cfg80211_alloc_event_skb in a module but you did not install or boot that kernel.
The old kernel is runnig with the new modules. Its harmless to the hardware but it won't work.
Look at the time and date in That's the time and date that the running kernel was built.
I suspect that you recall making a newer one.
If that's the case, we need to find out why the new kernel is not being used.
-- Edit--
The build time of the running kernel is at the top of dmesg
| Code: | | [ 0.000000] Linux version 5.4.72-gentoo (root@t420) (gcc version 9.3.0 (Gentoo 9.3.0-r1 p3)) #1 SMP Thu Nov 19 09:16:12 EST 2020 |

You are correct. I though I was loading a kernel built the 25th, but it seems to still be loading a kernel built the 19th. I'll re-check GRUB, but the only kernel in my /boot is the one built the 25th, so not sure how the 19th kernel is being loaded.
Just rebuilt again, but it still seems to boot the kernel from the 19th. Any idea how to locate and remove that kernel for good? the kernel in my /boot says it was modified the 27th. |

brb78,
You forgot to mount /boot for the kernel install, so it was correctly installed to the wrong /boot.
Your root partition has a directory called /boot. It behaves in all respects like any other directory. Its not an error to install kernels there.
You have a boot partition (no leading /) that must be attached to the filesystem tree at /boot for kernel updates.
This is where the bootloader expects to find kernels.
with boot not mounted should show nothing.
with boot mounted should show your kernels a grub directory and so on.
Grub has a nasty wart too. The newest kernel is not always the default, so you may need to use the menu to select the newest kernel.
