Ok, now running Linux Kernel 3.0.0(Ubuntu 11.10)[0]

After 3 days of uptime, i've had a new kind of crash(panic), this time in 
nf_conntrack_sip flush_expectations function. 

Trace and decoded trace attached, i still do not know how to read this in 
order to follow excecution and blame a particular kernel line of code. Guess 
compiling C into assembler on the fly is not in my skills bag.

I just want to check if this is kernel a bug, or may be there is something 
wrong somewhere else in my setup...
