Kernel Panic on 4.8-STABLE

Sun Apr 27 11:29:11 PDT 2003

Hello,

Recently, I've been having kernel panics on 4.8RC.  This made me upgrade
to 4.8-STABLE hoping that the problem would be solved.  Unfortunately,
I've had no such luck.  The panic happens about 1 hour after the machine
is booted.  Once booted and the panic occurs, the machine will reboot
itself for literally hours, until such time as the problem magically
goes away.  The box has been up for about a day now with no reboots.
I'm scared to play around with anything that might cause a reboot as I
can't afford this box to have downtime of ~8 - 12hrs (it's a remote
machine).

If additional information is required, please let me know.  The file
that the kernel is generated from is a pretty generic copy of GENERIC
with IPFIREWALL compiled in.

Any help would be appreciated.

Thanks,

Brad
