I have two Adaptec 2930CU (ultra narrow) cards. I modified the driver to
make them work in ultra mode. The card connected to my CDROM and MO drive,
operating at different bus clocks, does not behave well. Transfers stop
often for 10-20 seconds and it spits out warnings like these:
Apr 3 23:05:10 Jay kernel: scsi1:0:4:0: Attempting to queue an ABORT message
Apr 3 23:05:10 Jay kernel: scsi1:0:4:0: Command found on device queue

No probs with the old driver.

Can you elaborate on what you had to modify?

Please run your system with aic7xxx=verbose and send me the resulting
messages. You should also upgrade to v6.1.11 of the driver.

I just added AHC_ULTRA to the features of 7850
AHC_AIC7850_FE = AHC_SPIOCAP|AHC_AUTOPAUSE|AHC_TARGETMODE|AHC_ULTRA,
^^^^^^^^^^

Plain v6.1.11 hangs. It prints scsi0: blah blah scsi1: sdfdfgsg, I hear the cd
spinning up and nothing more. The system doesn't crash completely because the
cursor don't stop blinking (I don't use a hw cursor). I think it's just
waiting
something will never arrive.

What's the PCI id of the card you are using?

Did you apply a patch, or upgrade using the tar file? If the latter,
you're missing some changes to the SCSI layer that make the initial
bus settle delay implimentation more sane.

I'm not at home. If I remember right, it reported exactly the ID
of AHC_AIC7850 card, but I have a *PowerDomain* 2930CU (the Macintosh
version of the card) so pci IDs are likely to be different from the PC
version.

:-/ I'll try the patch this night.

Ok, I used the patch and it boots. Now CDROM and MO seem to work fine, but
when I work from the console I get this junk while accessing HD. It happens
much more frequently when the SCSI bus it set at 10MB/s than when it's at
20MB/s (with my small patch).
