I bet you got more output than that, didn't you? :-)

Now I know this must be a "scheduling while interrupts disabled",
but why not post the whole error message?

[ Reminds me of the other thread where someone thought just mentioning
the EIP without any backtrace / other messages was enough to resolve a
boot-time panic. I agree they're all magicians on this list, but Gods they're
not ... ]

BTW I don't see "mvSwIntrTasklet" anywhere on -rc6. Is this a -mm kernel?

Cheers,
Satyam
