Refer to hardware vnedor. Thats random corruption unless you are running
some very specific ppp stuff

UDMA has no bearing on this. If fiddiling with your bios has a change you
have a hardware problem. Linux 2.0 as opposed to 2.1 doesnt understand UDMA
so doesn't use UDMA so the drives don't do UDMA. Its all well planned - you
can stick your UDMA drive in a 386 with original IDE and it should all work
for example.

I think he needs to learn about the subdirectory ;). The box is probably taking
5 seconds to find a page - and no that should have no crash impact. at all.
Faster page handling may well make the customer much happier tho.

Those are not errors, just hints from somewhere that routing may be wrong.

That address is very suspicious and looks like a hardware flip. If I got your
offsets for timer_bh right you seem to have a memory problem that flipped
a bit (should be c00455b4).

First thing: Check the CPU fan seems happy, the memory and CPU seem to
be installed right and the BIOS settings and CPU voltage settings if any
are all right.

You said its a server so check the temperature if its full of 7200 rpm
drives.
