Grepping through the tree, "amd_gpio" sounds like
drivers/pinctrl/pinctrl-amd.c so maybe Linus might have an idea, CCed.
@Linus, the bugzilla entry has some more info on what happens.
@Austin: in the future, please do not CC everyone including the
postmaster on your bug. Now you're mass-spamming 50+ people
unnecessarily.
Thx.

I think it's unlikely to be related (seems like the affected drivers
are claiming their IRQs so this would have no effect), but good to
poke every angle of course.
This could be confirmed by enabling dyndbg to see if the "Disabling
spurious GPIO" message gets emitted.
There's also a debugfs dump file for amd_gpio, could be useful to
compare this before & after the failure.

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.
Yours,
Linus Walleij

Thanks for looking. I have it on a good authority that something like
that is happening now.
