Recording doesn't work at all with 3.19.1 without the patch. I've included an extract from syslog below of attempting to record with a clean 3.19.1 system (i.e. XHCI_AVOID_BEI quirk patch NOT applied, to state the obvious). I did mean to say in my original message that I would still release this patch even with the current known issue as it still improves the overall stability of the system.
