SubjectUhhuh. NMI received for unknown reason 20. ?
Hello,

I'm setting up a new server, it has a new Intel ServerWorks board with dual
1.266ghz P3 CPU's and 2gb ram.

I'm running into a few problems with it, crashing and strange error messages,
if anyone is familiar with these problems i'd appreciate a heads up on how to
handle them.

I currently have it running 2.4.19pre8, it would crash quite easily with 2.4.18
with redhat's kernel patches from their rawhide distribution while compiling
multiple kernels simultaneously. I will try to get a cable and capture the oops
with serial console.

Here is dmesg output..

Something that worries me:

Uhhuh. NMI received for unknown reason 20.
Dazed and confused, but trying to continue
Do you have a strange power saving mode enabled?

In the bios it had generate NMI on SERR and generate NMI on PERR, i disabled
them but still get this message when doing intensive things (compiling kernels).

Does this message mean bad things are certain to come or can it be harmless?

I'm going to leave it compiling kernels overnight and see if it's dead in the
morning.

# cat /proc/interrupts

Also with regards to the promise controller, it should be running at ATA100 but
is only reported at ATA33, it has the proper cables and the drives and
controller card are certainly capable, any idea?

Thanks for any help.
