Hi, Working with a new consumer laptop based on AMD Ryzen 7 3700U, all USB functionality goes dead upon suspend/resume (s2idle). Reproduced on linus master from today. <<<suspend>>> Freezing remaining freezable tasks ...

I tried a few things like making it try D3hot instead of D3cold (which is what it's aiming for even though it's not mentioned in the logs above), and disabling the suspend/resume actions taken by drivers/pci/pci-acpi.c without any improvement. Trying to sanity check other basic details I observe that this simple routine (to put it in D3 then D0) also fails: # cd /sys/bus/pci/drivers/xhci_hcd # echo -n 0000:00:03.0 > unbind # setpci -s 00:00.3 CAP_PM+4.b=3 # setpci -s 00:00.3 CAP_PM+4.b=0 # echo -n 0000:00:03.0 > bind bind then fails with: xhci_hcd 0000:03:00.3: enabling device (0000 -> 0002) xhci_hcd 0000:03:00.3: xHCI Host Controller xhci_hcd 0000:03:00.3: new USB bus registered, assigned bus number 1 xhci_hcd 0000:03:00.3: Host halt failed, -19 xhci_hcd 0000:03:00.3: can't setup: -19 xhci_hcd 0000:03:00.3: USB bus 1 deregistered xhci_hcd 0000:03:00.3: init 0000:03:00.3 fail, -19 As another test I was wondering if I could get Linux to put it into D3 and then go back into D0 without having to go through the whole suspend procedure, but even when I unbind it from xhci_hcd and set power/control to "auto" in /sys/bus/pci/devices/0000:03:00.3, runtime_status is "suspended" but Linux still leaves the device in D0 - is that expected? Any debugging pointers much appreciated. acpidump: https://gist.github.com/dsd/ff3dfc0f63cdd9eba4a0fbd9e776e8be lspci: https://gist.github.com/dsd/bd9370b35defdf43680b81ecb34381d5 Thanks Daniel
