Quite alot of our Linux boxes have been giving us grief lately crashing, with
errors from the syslog as listed below.
The machines are slackware based with 2.0.33 kernels installed.
The machines act as routers, with a satellite card and a regular NIC. When the
problem occurs, it seems to affect a number of machines, not just the one. The
machines are all of almost identical configurations.
I would just like to understand the error a little better before i decide to
upgrade quite a number of machines to a newer kernel (if thats even necessary),
or if i should investigate hardware faults.
Any input would be appreciated.
Regards,
Chris.
