data ASC/ASCQ of 0x04/0x01 (logical unit not ready, initialization in progress),
hang out for 5 seconds and return a RETRY THE OPERATION command. If we
get a check condition/sense data ASC/ASCQ of 0x04/0x02 (logical unit not
ready, initialization command required), send a polled/nosleep START UNIT
command and return a RETRY THE OPERATION command if that succeeds.
Don't send a START UNIT to a disk quirked as SDEV_NO_START. Don't send
a START UNIT to removable media. The reason for the latter is to not
just blindly spin up new (maybe changed) media.
I should note that I've successfully made this work with the ISP host
adapter so far. Other host adapters will need some work to be able
to manage or reasonably fail NOSLEEP/POLL commands while in this
state. Alternatively, the internal SCSI midlayer structure has got
to allow for more controlled error recovery (e.g., restart queues
controlled by the target driver).
drivers' sense handlers to return. Coincidentally one of them ends up
being ERESTARTSYS.
2) Add a SCSI_URGENT flag to xs structure- this allows host adapters that
do command tagging to do the right thing wrt a tag.
There is one change of note- build a list of completing commands in
ispintr and then say you're done- this avoids some re-entrancy issues
that had surfaced.
the recent bug where Multias around the world have been aborting back to
SRM with no message at all as they tried to attach a TGA or VGA console,
because the old mchkinfo pointer wasn't allocated prior to use.
And contrary to widespread rumour, this bug has nothing to do with my
LCA IDE mod...that worked just fine. "Not guilty."

Note: Most of this should be replaced with a com-port-detecting
heuristic better than the previous two.
