>Description:
	ZFS on JMicron USB2/eSata drive causes SYNC failures ... roughly 10 or so ... until system panic
>How-To-Repeat:
	Hook up drive, gpart partition per http://lists.freebsd.org/pipermail/freebsd-current/2007-April/070616.html, zpool, start copying files, panic
>Fix:

	Set quirk flag to stop synch attempts in umass.c .... eSata interface not tested (PCI Express card unsupported yet)
