On a 3 month old 7.0-STABLE system I find myself occasionally experiencing

Sep 18 01:02:47 <kern.crit> igor kernel: usb2: host controller process error
Sep 18 01:02:47 <kern.crit> igor kernel: usb2: host controller halted

My only permanently attached USB devices are my keyboard and mouse.  It's
happened most frequently on the bus to which my mouse is attached.  It's
been completely random so far - it'll happen for no apparent reason while
I'm using my workstation, particularly the mouse.  The only workaround I've
found so far is to reboot or plug the affected device(s) into a different
USB port.

Any ideas if this is a hardware issue or a software bug?  Anyone have
suggestions to try reproduce the problem?  Any point even spending time on
this with USB2 'round the corner?
