I have a similar problem. IRQ gets disabled and my wireless card stops working
after resuming from suspend.
Comment 5 James Ettle 2005-09-27 08:16:18 EDT
The problem persists with kernel 2.6.12-1.1456_FC4.
Comment 6 Dave Jones 2005-09-30 02:56:21 EDT
Mass update to all FC4 bugs:

An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel ( As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.

Please retest with this update, and update this bug if necessary.

Comment 7 James Ettle 2005-09-30 05:13:21 EDT
Using 2.6.13-1.1526_FC4 seems to solve this particular problem, but 8139too is
now broken on suspend/resume. It seems that the tranceiver isn't switched back
on: all I get is "link down" in the kernel log, and have to power down before it
works again.
