You got a DC390 (with an Am53C974 chip) not a DC390W/U/F (Sym53c8xx) ?
The Kernel 2.0.32 contains to possible drivers for the DC390:
tmscsim (DC390 - driver): v1.10
am53c974 (generic) : 0.5
The last one has a lot of problems, but the tmscsim should work.
What patch did you find. There is a patch to upgrade the driver from
version 1.10 to 1.11, which can be important to operate large HDs.
You can find it on student.physik.uni-dortmund.de/pub/linux/kernel/patches
Is your adapter correctly detected by the driver/kernel? Are there
harddisks connected to the SCSI adapter and are they recognized?
What does /proc/scsi/scsi and /proc/scsi/tmscsim/0 say ?

I believe the driver in 2.1.72 is the same as the one in 2.0.32, but it
didn't check recently. I sent my upgrade to the linux list some time ago,
but nobody merged into the kernel yet, AFAIK.

the am53c974 driver is known to have problems. You can try to download the
patch on student.physik.uni-dortmund.de/pub/linux/kernel/patches/misc-scsi
and define AM53C974_PROHIBIT_DISCONNECT if you want to start kernel
hacking ;-)

Please supply more info. If there is a bug in the driver, I'd like to fix
it ...
