In short, the problem seems to be that after resuming from s2idle, a PCI=20 xHCI host controller sometimes does not get MSI-X interrupts any more.=20=20 Setting a quirk flag that causes the driver to use PCI INTx interrupts=20 instead works around the problem, but it's still a bug. I have one of the affected systems but haven't tried to do any real=20 testing. --=20 You may reply to this email to add a comment.
