Description of problem:
Got first kernel crash in quite a while with 2.6.22-0.5.rc7.git2.fc8PAE:
Jul 4 13:58:26 localhost kernel: Uhhuh. NMI received for unknown reason b1 on
CPU 0.Jul 4 13:58:26 localhost kernel: You have some hardware problem, likely
on the PCI bus.
Jul 4 13:58:26 localhost kernel: Dazed and confused, but trying to continue
Jul 4 13:59:49 localhost syslogd 1.4.2: restart.
System was not being stressed: browsing, listening to internet radio.....
Running full Rawhide on Thinkpad X60.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
As the message suggests..
"You have some hardware problem, likely on the PCI bus."
This doesn't sound like a software problem. Random NMIs are usually a bad sign.
I got these frequently with the 'broken' e1000 drivers of a few months ago, and
not before nor since except this one.....
I filed this just in case there was some similar issue.
I'll close if you like....
Haven't seen a repeat.
