System still responds to some sysrq commands (sync remount boot show) - sysrq (term killall) has no effect. There's no chance to do any other keyboard input. No logs, no traps, no oops. Machine still responds to ping,(even port 22 stays open) but login via ssh is not possible. alsamixer, of course, is useless without the ioctl32 wrapper loaded - but does not crash the system then. So I suspect a problem in the ioctl32 wrapper. ====================================================================== ---------------------------------------------------------------------- eradicator - 11-20-04 10:23 ---------------------------------------------------------------------- A patch for one fix can be found here: http://bugs.gentoo.org/attachment.cgi?id=44333&action=view That is sufficient to get 'amixer' working. I'm going to go through and fix the other IOCTL now, and after it's tested, I'll post the final patch here for you. ---------------------------------------------------------------------- eradicator - 11-20-04 11:14 ---------------------------------------------------------------------- I updated the patch to fix a few more of the broken ioctl32 calls... http://bugs.gentoo.org/attachment.cgi?id=44338&action=edit All that's left is pcm32.c... hopefully I'll get to it sometime this weekend...
