Comment 3 John W. Linville 2007-08-03 09:51:39 EDT
Hmmm...did you try booting w/ the "irqpoll" kernel command line option?
Comment 4 Kaare Fiedler Christiansen 2007-08-03 12:01:09 EDT
I did, exactly same result (including the suggestion to try to boot with irqpoll...)
Comment 5 Kaare Fiedler Christiansen 2007-08-17 10:17:03 EDT
I just upgraded to the latest kernel in updates-testing,, and
that fixes the problem.

Will this kernel reach updates? In that case I consider the problem fixed.
Comment 6 Kaare Fiedler Christiansen 2007-08-25 16:37:19 EDT
Bug is fixed in new kernel from updates
