system fails to suspend as it resumes immediately

[Jurgen Schellaert]

My system fails to suspend or, to put it more accurately, wakes up again the very moment that it appears to have gone to sleep. The click that signals the drives parking is immediately followed by the whir that signals they are spinning up. I can try once, twice, three times in a row: the system will not go to sleep.

I do not know whether this is a new bug or something that has been present for a while. Today is the first time I decided to suspend instead of shut down or reboot.

In dmesg and journald logs, I find
xhci_hcd 0000:05:00.0: xHC error in resume, USBSTS 0x401, Reinit
xhci_hcd 0000:02:00.0: xHC error in resume, USBSTS 0x401, Reinit
I am not clear, though, whether this indicates the root of the problem or whether it is in fact a consequence. These message actually come AFTER the following, which appears to shows the CPU booting up again as soon as the disks have stopped:

Apparently it is an an ACPI thing. When I disable PTXH, suspend works as expected. Or rather, more or less as expected - the system does not wake up any longer when I touch the keyboard. I need to push the button on my computer case instead.

On a side note, the openSuse system that is installed on the same computer has recently developed the same issue. Oddly, the solution is different (same system, though): I have to disable XHC0.
