seems harmless because it seems to work fine.
I would poke Eric Biederman(sp?) about this one. Maybe its even solved
by the MSI-enable-related patch he posted in the past 24-48 hours.
Eric, Linus,
I tried the 3-patch series "[PATCH 0/3] Basic msi bug fixes.." and they fix this
problem for me. Were you expecting the OOPS in the first place? In any case, it
survived several suspend/resume cycles on both enabled (irq alloc'd and enabled)
and disabled devices (only initialized).
Jens Axboe was seeing the same problem, perhaps he can confirm the fix as well.
In any case, the patches have my blessing :)
