The suspend did however succeed, but it is possible that the USB subsystem may not have recovered from that failure.

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.

Comment 2 Martin Peres 2019-03-08 17:05:43 UTC

Not really happening anymore. Waiting a couple more CI runs before closing (drmtip_297).

Comment 3 Lakshminarayana Vudum 2019-06-14 12:26:42 UTC

Current drmtip is 305.
On an average this failure used to happen once in 11 drmtip runs, last seen drmtip 184. This bug can be closed as WORKSFORME.
