NMI error with kernel 2.6.33.5-112.fc13.i686.PAE

[Steven Stern]

When using the latest kernel, 2.6.33.5-112.fc13.i686.PAE, my machine
crashes with the message

Uhhuh. NMI received for unknown reason a0 on CPU 0.
You have some hardware problem, likely on the PCI
Dazed and confused, but trying to continue

And then it sits for a while and quietly digs itself a hole in the ground.

I've dropped back to kernel 2.6.33.4-95.fc13.i686.PAE to see if the
problem goes away.

One possible source of this is that (see other message), I'm now using
Network Manager to manage the wireless card and have changed from WEP to
WPA.   Googling indicates that this message is often associated with an
Atheros wireless card.

Anyone else having this issue?
