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
instruction pointer = 0x1f:0x80693e5

processor eflags = interrupt enabled, IOPL = 0

History

#1 Updated by tuxillo over 5 years ago

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

#2 Updated by tuxillo over 5 years ago

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

#3 Updated by rumcic over 5 years ago

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,
