Subject: re: Promise SATA-standby +selftest=hungdrive; Sil works...

This is with 2.6.26.5  (there are multiple other problems with 2.6.27[.0]).

The problem with the drive going "offline" doesn't happen with a
sil_sata(3124) controller -- so no need to unplug and replug...


I.e. when the drives are in standby, if smartd or a smartctl command
attempts to run a drive self-test (short), I get timeout errors from the
Promise controller (which hangs the sys if I try unplugging/replugging
the cable to the hung drive). 

The drives correctly spin up to speed and perform the short-test with
the sil controller.

It would seem there is a problem with the Promise controller or driver?
