2.6.15-rc5 and later: USB mouse IRQ post kills the computer post resume.

Hi Vojtech.

I have a HT box with USB mouse support built as modules. Beginning with
2.6.15-rc5 (maybe slightly earlier) a suspend/resume cycle makes the USB
mouse get in an invalid state, such that I get a gazillion messages in
the logs saying "unexpected IRQ trap at vector 99", or in some
alternately a hard hang. No work around found yet. Are you the right man
to talk to, or is Greg? (Spose I should cc him, so I'll add that now). I
can use kdb if it's helpful. Would you like my kconfig?

I should probably mention that I've also gained problems with DRM (it's
Radeon based), but I don't think they're related. I'll email BenH on
that separately.

Regards,

Nigel
