The libsas error handler has two fairly fatal bugs
1. scsi_sas_task_done calls scsi_eh_finish_cmd() too early. This
happens if the task completes after it has been aborted but before
the error handler starts up. Because scsi_eh_finish_cmd()
decrements host_failed and adds the task to the done list, the
error handler start check (host_failed == host_busy) never passes
and the eh never starts.
2. The multiple task completion paths sas_scsi_clear_queue_... all
simply delete the task from the error queue. This causes it to
disappear into the ether, since a command must be placed on the
done queue to be finished off by the error handler. This behaviour
causes the HBA to hang on pending commands.
Fix 1. by moving the SAS_TASK_STATE_ABORTED check to an exit clause at
the top of the routine and calling ->scsi_done() unconditionally (it
is a nop if the timer has fired). This keeps the task in the error
handling queue until the eh starts.
Fix 2. by making sure every task goes through task complete followed
by scsi_eh_finish_cmd().
Tested this by firing resets across a disk running a hammer test (now
it actually survives without hanging the system)

It's always been broken, but recent fixes actually made it do something,
and now the brokenness shows up as the resulting kernel simply not
working at all.
So it used to be that you could enable this config option, and it just
didn't do anything. Now we'd better stop people from enabling it by
mistake, since it _does_ do something, but does it so badly as to be
unusable.
Code to actually make it work is pending, but incomplete and won't be
merged into 2.6.25 in any case.

Sorry for the noise, but here's the v3 of this compilation fix :)
There are some places, which declare the char buf[...] on the stack
to push it later into dprintk(). Since the dprintk sometimes (if the
CONFIG_SYSCTL=n) becomes an empty do { } while (0) stub, these buffers
cause gcc to produce appropriate warnings.
Wrap these buffers with RPC_IFDEBUG macro, as Trond proposed, to
compile them out when not needed.

This patch (as1032) removes the Clear-Halt calls in
usb_stor_Bulk_max_lun(). Evidently some devices (such as the Oracom
MP3 player) really don't like to receive these requests when their
bulk endpoints aren't halted.
The only reason for adding them originally was to get an ancient
ZIP-100 drive to work. But since this device has only a single LUN,
we don't need to send it a Get-Max-LUN request at all. Adding an
unusual_devs entry for the ZIP-100 with the SINGLE_LUN flag set will
cause this step to be skipped.
