I get this stuff all the time in my logs from a single TDM400P in a p2.4
asus MB ...

Ouch, part reset, quickly restoring reality (0)
Power alarm on module 1, resetting!
Power alarm on module 3, resetting!

I also get all kinds of strange behaviour including no dialtone, low
audio volume, and faxing regularily fails.

I am assuming all of my problems are caused by interrupt sharing. I am
going tomorrow to move the card around until it gets on its own IRQ.If
you notice my kernel is not smp, I have other installs with the same
hardware working fine, because I am using hyperthreading with an smp
kernel, perhaps you should try that. 

Also, in some modules I use to be able to specify IRQ, why can't I in
the wcfxs module?
