I've had my DI-30 running with and without DMA throughout osst development,=
 =20
and never seen detection problems caused that way.

Are you sure ide-scsi is loaded before osst? What does lsscsi say? I have

[root@fallguy root]# lsscsi

If everything checks out, can you make an osst module with DEBUG enabled an=
d =20
send me all log messages produced?

By the way, did anything change from yesterday to today? Kernel upgrade?
What distribution/release/kernel-version are you running?
