Hello all,
I am currently running:
FreeBSD <hostname excluded> 3.0CAM-19980712-SNAP FreeBSD
3.0CAM-19980712-SNAP #1: Tue Aug 11 23:55:17 CDT 1998
I attempted to apply to 0716 patch but it appears it really was already
installed with the 0712 snapshot-
cam_ccb.h:#define CAM_VERSION 0x4C /* Hex value for current version
*/
is the same for both 0712 and 0716 (If this isn't a good way of
determining this, please let me know). The patch fails and wants
to assume -R, so it really looks like it is already 0716.
This is a dual PII-400 box with 4 scsi hosts:
1. Buslogic 958D (ultra/wide/diff)
2. Buslogic 946C (narrow)
3. Qty (2) 2940UW's
My problem with the 958D is:

All disks are recognized (which is new from the standard scsi drivers
which don't realize the 958D is a wide controller), but they are syncing
at 3.300MB/s ??? These disks should be able to do 40MB/s (ultra wide
diff).
The second issue is on ahc - I don't have specifics quite yet but I'm
getting hangs on this disk which cause the entire system to hang.
The next time it hangs I'll capture some console messages. From
memory is was something like "Timed out due to another timeout" and
referenced aha:da1. I had a similiar issue under linux and was forced
to disable tagged queing on my microp 4743SS drives. I'm not quite
sure how to do that under fbsd.

Any insight would be appreciated :-)
