Oh...

I tried 2.6.27-rc2 with that patch reverted and NAPI disabled,
but that didn't work either, so it seems it's something a level
higher. (No way that that last patch could cause this...)

You said off-list that I may want to check if there is any aspm
related message in dmesg. Well, I get this:

  Pre-1.1 PCIe device detected, disable ASPM for 0000:00:1c.1.
  It can be enabled forcedly with 'pcie_aspm=force'

So I guess it's unlikely that it causes any problems, except
if the driver assumes it's always enabled. Booting with
pcie_aspm=force didn't change anything (though strangely
enough I still get the same message as above).

All in all I'll wait till rc3 and see how things are then.

Thank you for the help,

Indan
