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. ====================================================================== ---------------------------------------------------------------------- sjoerd - 11-21-04 17:44 ---------------------------------------------------------------------- A friend of mine just tried both my patches on his blade 100. The cvs patch against 2.6.10-rc2 did indeed freeze his machine. Linux 2.6.9 with the patch that was on the sparclinux list worked fine.. So either i forgot to forward port something or something else was broken.. On a side note, his sound didn't have any distorsions. So the bad quality i'm hearing is the alsa driver for my card and not the 32 bit emulation layer ---------------------------------------------------------------------- eradicator - 11-21-04 21:26 ---------------------------------------------------------------------- ok, good point about the code testing on different archs, and you're right about the speedup being minimal... I'm just alays nervous about changing something for other architectures when I can't test it... I still want to leave in the #ifdef stuff around the indirect code as we didn't really "fix" that so much as forced it to return an error... I'll try out 2.6.9 with your list patch and compare to see what's going wrong... Also, I'm not familiar with "__attribute__((packed));" What does that do, and why was that removed from the ends of the structs?
