[vox-tech] SCSI woes

Hello --

I've got a Promise Ultratrak RM8000 array up and running on a RedHat 6.2
system with a 2.4 kernel.  I'm using the sym53c8xx driver.  In dmesg, I see
lines like:

sym53c1010-66-0-<0,*>: FAST-20 WIDE SCSI 40.0 MB/s (50.0 ns, offset 31)
sym53c1010-66-0-<1,*>: FAST-20 WIDE SCSI 40.0 MB/s (50.0 ns, offset 31)
sym53c1010-66-0-<2,*>: FAST-20 WIDE SCSI 40.0 MB/s (50.0 ns, offset 31)
sym53c1010-66-0-<5,*>: target did not report SYNC.
sym53c1010-66-0-<5,*>: target did not report SYNC.
sym53c1010-66-0-<6,*>: target did not report SYNC.
sym53c1010-66-0-<6,*>: target did not report SYNC.

(0, 1 and 2 are internal SCSI disks; 5 and 6 are the RM8000)

This leads me to believe that the card is defaulting to asynchronous mode
which is causing very slow read/write times for me.

The SCSI BIOS seems to recognize the drives, as they all show up in the
configuration dialog.

Can anyone offer any guidance?

Thanks,
