The controller isn't the problem, it's CAM. You could try this patch:
--- /sys/dev/mly/mly_cam.c Sat Mar 3 01:40:26 2001
+++ mly_cam.c Wed May 30 12:46:09 2001
@@ -132,6 +132,9 @@
/* initialise the CCB queue */
mly_initq_ccb(sc);
+ /* hide the physical channels */
+ sc->mly_controllerinfo->physical_channels_present = 0;
+
/*
* Allocate a devq for all our channels combined.
*/
which will hide the physical channels from CAM. This means that non-disk
peripherals on the controller SCSI busses won't work, which will get me
another set of whining complaints from different people. 8(
Please, someone actually acknowledge that they're hearing me on this? I've
sent over a dozen responses to complaints about backplane issues, and
heard *nothing* in reply.
Regards,
Mike
