When the driver reads state values from the hw it might happen that
different values are read in subsequent reads and this can cause problems,
this may lead to a timeout in this function and a non working adapter.

Hi all,
I have posted almost the same fix back 2011
http://www.spinics.net/lists/linux-scsi/msg50624.html
now it looks like someone was really hit by the hw read race.
This patch is split into two part - the first patch fixes the actual race,
the second is a bonus, it just removes some almost

Move up the logging of messages and generation of uevents
for certain sense codes before checking for TEST UNIT READY
commands not generated by the mid-layer, so they won't be

This bug can be easily reproduced by havin two machines with one fibre
channel card each.
Install scst on one machine (as target) and conenct the other one to this one
(via two cables).
Than add

The abort/reset lowlevel return codes had changed with the new

Change reset handling to clear queues only, do not attempt to
call done() on each command aborted by the reset. The EH code
should do that for us.

All,
please review the following patches to the m68k Atari NCR5380 SCSI code.
The first patch is my corrected version of Arnd Bergmann's sleep_on removal RFC
series (2/16), tested on my Atari Falcon. Geert, please take this one through
the
linux-m68k tree so Arnd's sleep_on remove can go
sleep_on is known broken and going away. The atari_scsi driver is one of
two remaining users in the falcon_get_lock() function, which is a rather
crazy piece of code. This does not attempt to fix the driver's locking
scheme in general, but at least prevents falcon_get_lock from going to
sleep when
In case a SCSI command is queued from softirq context, and another
driver currently holds the ST-DMA lock, tell the SCSI midlevel to
hold off queueing commands for now. Midlevel will resume play later.
