Make sure that you have VirtualHDIRQ=FALSE in system.ini; this is apparently
required for scsi controllers, which are bus masters.  I've an Adaptec 
controller in my machine, and it all seems to be quite stable.  I tried
QEMM 5.11, but it slowed the disk a lot and I ripped it.  If I understand
(and recall) the docs about that setting, it only affects enhanced mode, and
has to do with how disk interrupts are fielded.  I also recall reading some
info that said you HAD to have Smartdrive loaded with a SCSI controller so that
it could do double buffering of the controller.  Make sure you have both of 
those and see what happens.
