Subject2.4.19 - Promise TX2 Ultra133 (pdc20269) sticks at UDMA33
Date
I'm running 2.4.19 with a Promise TX2 Ultra133, but even though the card BIOS reports 
UDMA mode 5/6 on the drives, they are reported as UDMA33 by the kernel.

Trying hdparm -X69 after boot gives the message "Speed warnings UDMA 3/4/5 is not functional."

The IBM drive is only ATA100, but the Maxtor (just fitted) is definitely ATA133.

Any ideas?

Unfortunately, I'm running with XFS, so I'm a bit restricted in what kernel versions I can run.

Thanks,
Barrie
