A similar workaround for the suspend/resume problem is needed for yet
another ASUS machines, P6X models.  Like the previous fix, the BIOS
doesn't provide the standard DMI_SYS_* entry, so again DMI_BOARD_*
entries are used instead.

Applied, but this is getting suspicious.

It looks like MSI generally is not restored properly on resume on these
boards, so maybe there simply needs to be a generic PCI quirk for that?

Yes, I wondered that, too.
But, e.g. HD-audio should use MSI on Intel platforms, and if the
problem were generic, it must suffer from the same issue, and I
haven't heard of such, so far.  So it's likely specific to some
limited devices, as it seems.


Thanks!
