Hi,


uname -a

Linux 2.4.21-27.0.4.ELsmp #1 SMP Sat Apr 16 18:43:06 EDT 2005 i686 i686 i386 GNU/Linux


This machine keeps rebooting every couple of weeks, looking through the logs, I can't see anything obvious. It seems to be a Kernel panic but I'm having problems identifying why. Here are the the log entries at the moment the machine reboots.

Any help will be very much appreciated.

Thanks and all the best
