TWO different machines, identical behavior.
KDM comes up, and everything appears normal. The instant a single key is pressed in the password field, the machine goes dead (screen black, network connections down, does not respond to pings). After rebooting, there is no indication in the logs of what happened.
2.6.34 did not have this problem. |

| 2.6.35.1-4 runs fine here with KDE 4.4.5 at a 32bit x86 ThinkPad with integrated Intel graphic card. Did you tested the kernel with a straight xdm login (or even startx) ? |

I meant the stable one, "of course" (implied, but I do admit, not obvious). |

You're still being ridiculously vague. Gentoo patchset, or vanilla, or what? We're not mind-readers. I use pf, for example.
Also, the stable one today might be different to the stable one tomorrow. So, state a proper version number. |

gentoo-sources-2.6.35-r4
None of the vanilla-sources on the 2.6.35 series are stable on any architecture. |

Hadn't tried that before (and didn't get very far with it). Much to my surprise, the same thing happens at the console - the first key pressed to type in the username borks the system, although this time I do get a very long stack trace (of which I can only see the tail end).
I don't know any way of capturing that, but "cpu_idle" stood out several times. |

What do you call x86 here?
| Code: |
$ grep KEYWORDS /usr/portage/sys-kernel/gentoo-sources/gentoo-sources-2.6.35-r4.ebuild
KEYWORDS="~alpha ~amd64 ~arm ~hppa ~ia64 ~ppc ~ppc64 ~sh ~sparc x86"

Make a photo and attach it onto a Gentoo bugzilla report. |

I run the zen sources 2.6.35 with X 1.9.0 and it has been rock solid.
What version of X, which video card and driver version?

OK, I tried that (but I had a lot of trouble getting a decent picture. Is this good enough to be useful?

No, I'm afraid.
To give the devs a good starting point, prabably you should increase the font size within /etc/conf.d/consolefont and then try it again. |

Neither 2.6.35 (gentoo sources or vanilla-sources) or 2.6.36-rc (git) will work on my i7 machine. Well to be exact it does work however it turns my 3.0GHz i7 so slow that typing is like a 300 baud modem..
https://forums.gentoo.org/viewtopic-t-838842-highlight-.html
And the problem persists with all power management disabled in the bios.
2.6.34 gentoo-sources on the same machine works fine.

Interesting - I observed this with my ThinkPad T400 (Core2 Duo) with an early 2.6.36-rc1 version, but it disappears with a later release candidate and therefore I ignored it. |

No, both machines are desktops. One is a P4 and the other is a Core 2. |

The i7 re-introduces hyperthreading, which results in 8 virtual cores. do you have hyperthreading enabled or disabled in your kernel?

Enabled, I see all 8 cores. This works on 2.6.34. I can try disabling that this evening (3 or so hours from now) and see if that fixes the issue.

I'd like to note two things.
1. (I guess you did it) It's time to migrate from "< > ATA/ATAPI/MFM/RLL support (DEPRECATED)" to "<*> Serial ATA and Parallel ATA drivers". It's easy - just reconfig you kernel, then update your bootloader config (e.g. grub.conf) and /etc/fstab in favour of change ALL /dev/hd. devices to /dev/sd. devices.
If something goes wrong - you need to reboot from a LiveCD. Also your old kernels which use /dev/hd. devices now became useless.
2. (It's your case I belive) You should (try) "adjust" the version of udev you use. There are 3 options here:
- use udev-149, mask udev-151-r4 (if you have ATA (PATA - just another name) disk and using deprecated ATA drivers)
- use udev-151-r4, add USE flag "devfs-compat" (if you have ATA (PATA) disk and using new PATA drivers)
- use udev-160 (if you have ATA (PATA) disk and using new PATA drivers)
Also, It's good idea to use kernel 2.6.35+, since, for example, 2.6.34 not working with old ATA /dev/hda drivers and udev-151-r4, but works with the new drivers and udev-151-r4 
It was tested on: vanilla-sources, x86 arch, Intel Celeron and PIIMMX. I do believe neither amd64 arch nor SATA disks aren't effected.
I do hope this will help. |
