Description

While completing booting (starting kdm, FAH, etc.) the machine panicked. I
uploaded the dump to leaf:~rumko/crash/23.10.2007.

The panic msg:
Fatal trap 7: system forced exception while in user mode
mp_lock = 00000000; cpuid = 0; lapic.id = 00000000

frame pointer = 0x2f:0xbfbff8bc
code segment = base 0xff800000, limit 0x7, type 0x13 = DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, IOPL = 0
current process = 764 (FAH504-Linux.exe)
current thread = pri 6
<- SMP: XXX
trap number = 7

Rumko, the dump is not on leaf anymore. Was it deleted?

Won't fix. Lack of information. Rumko told he'll report back again in the case
it happens with latest.

Got another panic ~1 week ago with the same message. This time I was updating my
system (using pkgmanager) and playing with X (change xorg.conf, restart X, repeat).

The dump is at leaf:~rumko/crash/exception/

Hi,

Xorg is quite used lately in dfly but no panics are reported due its usage so closing this one.

Cheers,
