Uhhuh. NMI received for unknown reason bX on CPU 0.
You have some hardware problem, likely on the PCI bus.
Dazed and confused, but trying to continue....
Can we fix this messages somehow it's kinda misleading, it
suggest that the hw is failing when in 99% it's a buggy driver..
When I read "You have some hardware problem" I think
my hardware is failing and I need to backup my data
and replace the part that is failing....
Better would be..
Uhhuh. NMI received for unknown reason bX on CPU 0.
I have been feed [ driver X ] buggy driver ...

Why do you think it is a faulty driver? For me it seems that most
obvious reason for triggering a NMI is a buggy hardware.
I think it's a faulty driver because it varies on which kernel
i'm running whether I see this in my logs or not FC-6 - FC-8.....
Hence logic says that something that is being change between kernels
are causing this otherwise the kernel would ALWAYS being reporting
this...
The first time I saw it was when I made some custom kernel with hacks
to get better dvd playing experince in FC5 ( dvd playback was lagging )
When I ran the stock kernel in FC5 I did not receive the message..
Also see https://bugzilla.redhat.com/show_bug.cgi?id=213227
Follow the Ubuntu links as well..
If this error is accurate, as in a buggy driver/wrong driver being used
( hardware configuration error ) which behaves similar but not exactly
the same
( then the detection process on which driver to use is buggy ) cant
cause this error
( trigger false signals on the NMI circuitry )
then ok I need to replace my hardware..
But if it can the msg needs rewriting...
If anyone can tell me how I can *debug* it further
I'm all ears..
