The Advanced Error Interrupt Message Number (bits 31:27 of the Root
Error Status Register) is updated when the number of msi messages assigned to a
device changes. Migration of windows 7 on q35 chipset failed because the check
in get_pci_config_device() fails due to cmask being set on these bits. Its valid
to update these bits and we must restore this state across migration.

q35 isn't part of 1.1 so why do we want this patch there?

Looks like we don't,  I dropped this patch now.

Actually...  isn't it the same when you use ahci device?

Thanks,
