Re: OOps - very obscure

Florian,

What is the kernel version?  Your symptom seems to remind me the corrupted s0
bug in several syscalls. The bug is fixed around test9 I believe.  Check for
"save_static_function(sys_sigsuspend);" statement in arch/mips/kernel/signal.c
file.  If you have it, then you don't have the bug.
