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. ====================================================================== ---------------------------------------------------------------------- tiwai - 11-25-04 12:22 ---------------------------------------------------------------------- copy_in_user() is available on other architectures (at least x86-64 and ppc64) with 2.6.7, either exported or inlined. I found some thinkos in the last patch. The new patch is attached. If this still doesn't work, please check via strace which ioctl fails. ---------------------------------------------------------------------- eradicator - 11-26-04 08:26 ---------------------------------------------------------------------- ok... your patch is now letting me use the mixer, but playback causes a system lockup...
