Description:
There are 2 patches for xhci that fix excessive kernel messages and and a failure to write to USB (3.0?) storage devices. In my case messages like bellow kernel: xhci_hcd 0000:04:00.0: Too many fragments 64, max 63 systemd-journal[287]: Missed 6866 kernel messages flooded the journal so much that the maximum 1.3GB of it contained only those messages. More important the machine gets stuck with 100% CPU usage, data is lost and the offending processes can't be killed requiring a reboot. The patches are queued for 3.14 which seems a bit distant. I tested the patches with ABS and the problem is fixed.
