Title:
xhci hangs; reset results in NULL pointer dereference
Status in linux package in Ubuntu:
Incomplete
Bug description:
Now and then, my xhci bus will hang, resulting in these kinds of
messages in dmesg:
[252220.002102] xhci_hcd 0000:00:14.0: xHC is not running.
[252220.037491] xhci_hcd 0000:00:14.0: xHCI host controller not responding,
assume dead
[252220.037500] xhci_hcd 0000:00:14.0: HC died; cleaning up
[252220.133794] usb 1-2: USB disconnect, device number 2
[252220.135042] usb 1-7: USB disconnect, device number 3
[252220.137455] usb 1-8: USB disconnect, device number 4
[252220.243317] usb 1-9: USB disconnect, device number 5
Usually, I can fix this bij resetting the bus by calling a script
reset-xhci:
for xhci in /sys/bus/pci/drivers/?hci_hcd ; do
cd $xhci
echo Resetting devices from $xhci...
for i in ????:??:??.? ; do
echo -n "$i" > unbind
echo -n "$i" > bind
done
done
But doing this today resulted in a kernel bug:
[252243.401814] xhci_hcd 0000:00:14.0: remove, state 4
[252243.401887] usb usb2: USB disconnect, device number 1
