xHCI host controller not responding, assume dead
Today, a number of USB devices were unavailable for no apparent reason.
Having a terminal always visible running dmesg -w the following showed up:
xhci_hcd 0000:0b:00.3: Abort failed to stop command ring: -110
xhci_hcd 0000:0b:00.3: xHCI host controller not responding, assume dead
xhci_hcd 0000:0b:00.3: HC died; cleaning up
Hmm, assume dead... that doesn’t sounds good.
