Hello List,
on shutdown the following lines are displayed, but _not_ logged to
/var/log/messages:
Going to halt the system ...
Synchronizing SCSI caches: sda FAILED

Your device cannot handle SYNCHRONIZED_CACHE command which flushes
Seagate ST52160N device cache during shutdown introduced in recent 2.5.
I think the below patch for 2.5.50 (and current BK) suppresses such
failure message.
