Thinkpad 600e interrupt storm

[list at understudy.net]

Hi ,

I have loaded FreeBSD 5.3 on my Thinkpad 600e. However I am getting two errors
on boot up that concern me.
Interrupt storm detected on "irq10: pcic1"; throttling  interrupt source
and
Interrupt storm detected on "irq11: pcic0 uhci0"; throttling  interrupt source

I have been through google and not found a workable solution to removing the
errors. If anyone has an answer could you share it please.

Sincerely,
Brendhan
