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. ====================================================================== ---------------------------------------------------------------------- weeve - 11-19-04 05:45 ---------------------------------------------------------------------- >>From a recent thread on the sparclinux mailing list , get_fs() == KERNEL_DS will always cause a SPARC64 machne to hang. ---------------------------------------------------------------------- rlrevell - 11-19-04 05:55 ---------------------------------------------------------------------- That mailing list thread refers to an ALSA patch that fixes the problem and which was not posted.
