Very Computer

This dual CPU system will stay up for a few days, and then it starts reporting these
errors to the console, shortly after these messages start appearing it will lock up.
Below is the output from dmesg. Below that is my system info. Is there a patch for
this? This is the standard redhat 8.0 kernel (2.4.18-14smp).

Thanks,

You really should get your system up-to-date.

There have been a number of updates to the
redhat kernel since the original release.

Best Regards,

it. Could be hw or sw. The best place to file bugs on Red Hat kernels
is http://bugzilla.redhat.com. There is a newer kernel update but I
don't know if it fixes anything you might be hitting from the info
given.
