I have no clue, someone with deeper understanding of AMDs bridges
and stuff need to look at this. Since it dies after a while I would
suspect power management by the BIOS. (Off the top of my head.)
SInce I guess these systems use BIOS ACPI for all PM.
If someone from AMD could pick up this bug, that would be great.
