As told in answer #32 in bug 197521, i open a new bug for my problem. I copy my description from the other bugreport: My problem is, i cannot give much information and i am also not able to reproduce the crashes. But for me hardened-sources-.26.23 and hardened-sources-2.6.23-r1 do somehow crash. After that, i cant do any keyboard input, but still use my mouse and do some things on the desktop. But if i try to kill my desktop, the screens goes black and i cant do something any more. I can login over ssh and do some things, but e.g. one time i tried to compile something and got an <defunct> emerge process. This happens with running X+e17(cvs) and also without running X. I do not get any kernel oops or any other message about the crash, only the cursor does not blink any more (if i am on the konsole while the crash happens). This is on a hardened/amd64/multilib profile with ~amd64 keyword. additional: tested hardened-sources-2.6.23-r2 today and had a crash again, this time nothing did react, no keyboard response, no network activity (ssh or similar not working any more). Also had a crash with hardened-sources-2.6.22-r7, but in this case i was able to ssh in and it did run for a couple of day so its at least the more stable version for me.
You tried running memtest86 on your memory ? Seems more like a defective memory to me.
Oh, I'd also like to see the .config of your hardened-sources.
Created attachment 139464 [details] .config did not try memtest so far, but will do it to exclude memory as a source
2 hours memtest (4 complete test) and no error
did some more tests: compiled hardened-sources-2.6.23-r5 with gcc-3.4.6-vanilla => crash compiled gentoo-sources-2.6.23-r5 with gcc-3.4.6 => crash one interesting detail: if this crash happens and network still exists, i can log into the machine using ssh. But once i try to emerge something, it stops at "preparing to unpack" and i get a defunct ebuild.sh.
Seems like the crash i had without X could have some other reason, as i cannot reproduce it and all crashes since then happend with X running. This where so far up to xorg-server-1.4.0.90-r2 and also the stable version up to xorg-server-1.3.0.0-r4
Ok, new crash, some new details: -I did not have X running, so perhaps X could change the time until it happens, but not the bug itself. A "emerge -uDN world" was running before and finished before the cursor freezed and no more input was possible. -I have a <defunct> java process (running freenet from freenetproject.org on 64bit-java). -I can still ssh in and watch top or browse directorys. And another strange point: Also no other keyboard input works, strg-alt-entf did sent a "reboot"-command to the os, also it only starts to shut down and nothing more happens (and no interactions are any more possible).
Seems like the problem is solved with kernel-2.6.24. Running latest gentoo-sources for over 2 weeks now without this crashes. Imho the problem was the old bcm43xx driver or related to it. As there is no more upstream development for this driver, i will mark this one as wontfix.
