Subjecttmscsim.o INQUIRY inconsistency in 2.2.19

Vendor: SEAGATE Model: ST15230N Rev: 0638

Commands in Queues: Query: 0:

Often (but not always), on boot, I get Sync as "No" for the hard drive (Idx
0). Doing "echo 'inquiry 0' > 0" always fixes the problem after boot but for
some reason, the driver doesn't (always) pick up on this at boot time. It
doesn't seem to matter if it's a boot up from power-off or soft reboot.

The drive, Seagate Hawk, support synchronous operation and sync negotiation.
