[1.] One line summary of the problem: kernel panic/oops system hangs
[2.] Full description of the problem/report:
After some random period of time (from 1 hour to several days) kernel
receives an 'oops' and dies. Requires power cycle to recover. I've a few
of the 'oops' output saved and converted with ksymoops if required
(included one below) Error appear to be in the iptables
connection_tracking actually.
[3.] Keywords (i.e., modules, networking, kernel):
networking kernel oops
[4.] Kernel version (from /proc/version):
Linux version 2.4.31 ([email protected]) (gcc version 3.3.5
(Debian 1:3.3.5-13)) #1 SMP Sun Mar 12 15:09:22 GMT 2006
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
