Please provide more useful info.  At the least, we will need
panic and/or oops data from the console (for which you might
need to attach a serial console line).


Comment 2 Carlos Martinez 2004-11-08 22:59:46 UTC
Well, by now I can tell you that we are running 2.4.21-20.ELsmp 
kernel (RHES AS3 U3) and all the machines are freezing every day. The 
last that you can see in the screen is "Re-booting due to 
unexpected NMI at 0000:0000". I was looking for help and found some 
similar problems with this kernel.Do you have some other newer and 
fully tested kernels ??
I'll get the data from the console.
Tks in advance.

This same problem is happening on our system xSeries 336 + (
2.4.21-27.0.2-ELsmp ) too.



Comment 4 Dave Anderson 2005-02-09 19:20:58 UTC
Doing a cscope search on the kernel sources, and the doing a
"strings <kernel> | grep NMI" on both vmlinux-2.4.21-20.ELsmp and
vmlinux-2.4.21-27.0.2.ELsmp, this message does not appear to be
coming from the kernel:

  Re-booting due to unexpected NMI at 0000:0000

Is this message being generated by the BIOS?  And what does the
message requesting "See the system error log" actually refer to?




Comment 5 Stephen P. Schaefer 2005-02-14 20:48:09 UTC
I'm seeing this problem on a dual Xeon IBM x346 (model 8840).  There
is no kernel oops, and after the BIOS goes through checking memory,
initing the two Broadcom ethernets and getting a "Status=OK" from the
ServeRAID-7k, I get the message "Unexpected NMI at 000:0000".  I don't
think the kernel booted yet - there were no messages from GRUB.  In my
case it feels like a hardware to problem to me.  Whether the kernel is
creating inauspicious circumstances is anyone's guess.
