Recently I got similar problems with the AM53C974 driver included in
2.0.x. I was using a Tekram DC390 card together with an optical drive.
Reading from the drive was generally ok, but writing would cause these
"scsi_free:Trying to free unused memory" errors almost immediately,
followed by a complete freeze. Since the drive worked fine under
Win95, a driver problem was suspected. At their site ( I
found a recent driver (Oct. 96) that seems to work fine under 2.0.23.
If you're using this type of adapter, give it a try.
