In my case there was none. When first observed I simply updated
sources and tried to rebuild kernel and world, thinking the problem
would be corrected eventually. Only after several iterations
(so, weeks or a month) did I report a problem, and misidentified
it at that. Your observation that the crash occurred before, not
after, reboot was an important correction.

There's a git bisect in progress on the host using a usb-sata 
bridge. The second host with a usb-pata bridge is tracking 
-current to see if the problem is "overcome by events". 

The patch will be tried on the usb2-pata host if the problem 
persists as it will conclude faster than the bisect process.

Thanks for writing!
