commit a0d4922 ("USB: fix up suspend and resume for PCI host
controllers") causes a lot of these two lines to be logged:
uhci_hcd 0000:00:1d.2: host system error, PCI problems?
uhci_hcd 0000:00:1d.2: host controller process error, something bad
happened!
Normally they appear on resume after suspend to disk, but sometimes I'm
not even sure I had to suspend to disk to see them. Also, it seems like
they don't trigger if X has not been started, or at least they are much
less likely to.
Reverting the patch restores normal operation.
No USB devices were attached BTW.

So this one has already been reported [1]. There was some mentioning of
a patch to try out instead of reverting, but I couldn't find it.
Rafael, did you have something else to suggest or can we please get a
revert of this one upstream asap before too many are wasting their time
on this one?

That fixes suspend to disk for me.
Thanks Rafael, you really do an important and fantastic job on the
regression work.
