that's good.  i hope i've corrected the debug prints.
in this case drive n is sdEn.

unfortunately, task=50 and sstat=113 are what we want, but the
old 9load driver just isn't getting the picture.

this is also bogus.  there's no drive to reset.

bug.  probablly a drive power mgmt problem.  was this a seperate boot?

also,
> init: starting /bin/rc
> sdE0: i/o error d0 @206,672

that is Eicrc | Eunc | Eidnf =
	interface crc error,
	uncorrectable read error
	no user-accessable sector.

this is a jmicron bug.  i haven't yet had in my possession a jmicron
controller, so this will be interesting, but the new driver does have
code to work around this very issue.
