freebsd stable - Nov 2003 - kern/57174: 4.9-PRERELEASE panic: ata_dmasetup: transfer active on this device!

Hello,

A couple days ago I faced with a problem similar to described in PR
kern/57174 (see subject).

But there are some differences:
1) hw.ata.tags=0 on my system
2) problem appeared when i replaced a Seagate Barracuda 30G with Maxtor
DiamondMax Plus 9 200G, attached to CMD648-based PCI adapter.
3) system is 4.9-RELEASE

Note that:
1) Maxtor is the only drive attached to CMD
2) When I tried to attach Maxtor to the free channel of Promise U66
controller, the kernel just panics at ATA-probe (very similar to PR
kern/57369)
3) BIOS on CMD648 is obsolete (sees only 64G of 200), but removing BIOS chip
does not change things - and I know that this controller works fine without
BIOS under FreeBSD 4.8 with 2*Maxtors 80G.

Workaround is to disable UDMA on this drive (atacontrol mode 4 pio4 pio4),
but this significantly slows down system, and another errors continue to
appear (ad8: READ command timeout...)

Below is a /var/run/dmesg.boot for this system. I can also make a backtrace
of chashdump if needed.
