This is from a Linux 2.0.27 kernel, 5 different oops, the only change to the
kernel is to support 1024 fds (maybe it is the 1K fds patch, anyone have one
that has worked well for them?) Seems to be with timers, the other thing
noticable about this machine is that is has a severe problem keeping time,
I mean it will lose *HOURS* daily.
