Public bug reported:
I have one system where I use rtcwake in a cron job to have it sleep and
wake up at certain times of day. I upgraded from linux-
image-5.4.0-29-generic (5.4.0-29.33) to linux-image-5.4.0-66-generic
(5.4.0-66.74) and the rtcwake command no longer works, failing with
'write error'.
>From dmesg, the reason for this is the inability to suspend a usb
device:
[240303.355471] PM: dpm_run_callback(): usb_dev_suspend+0x0/0x20 returns -16
[240303.355475] PM: Device usb4 failed to suspend async: error -16
usb4 appears to be the xhci controller?
# ls -l /sys/bus/usb/devices/usb4
lrwxrwxrwx 1 root root 0 Mar 1 09:36 /sys/bus/usb/devices/usb4 ->
../../../devices/pci0000:00/0000:00:14.0/usb4
# lspci -s 00:14.0
00:14.0 USB controller: Intel Corporation 9 Series Chipset Family USB xHCI
Controller
System is an older ASRock H97M-ITX/ac board. It does have a quirk which may be
relevant - it reports what I think is every port as having an over-current
condition on boot:
# dmesg |grep over-current
[ 1.083073] usb 1-1-port3: over-current condition
[ 1.115054] usb 2-1-port5: over-current condition
[ 1.138911] usb usb3-port7: over-current condition
[ 1.299066] usb 1-1-port4: over-current condition
[ 1.331053] usb 2-1-port6: over-current condition
[ 1.354886] usb usb3-port8: over-current condition
[ 1.570911] usb usb3-port9: over-current condition
[ 1.786908] usb usb3-port10: over-current condition
This occurs even when _no_ usb devices (or even internal cables!) are
plugged into it (including removing the internal wifi/bluetooth card).
It occurs on both the older (working) and newer (failing) kernel.
Based on a couple of random internet posts I tried adding
usbcore.autosuspend=-1 and hpet=disable to the kernel command line, but
neither seemed to have any impact.
