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..
