Title:
USB dies after random time
Status in linux package in Ubuntu:
Confirmed
Bug description:
Running Ubuntu 18.04 with the 4.15.0.29 Kernel (the 4.17 line produces
several ACPI errors and is not really usable for me) on my DELL XPS 13 always
results in randomly ding Bluetooth and camera.
Dmesg gives the following output
[ 1933.132015] xhci_hcd 0000:00:14.0: xHC is not running.
[ 1933.151360] xhci_hcd 0000:00:14.0: xHCI host controller not responding,
assume dead
[ 1933.151379] xhci_hcd 0000:00:14.0: HC died; cleaning up
[ 1933.252202] usb 1-5: USB disconnect, device number 4
[ 1933.253443] usb 1-7: USB disconnect, device number 5
Can anybody help?
