Hi,

Was searching through the archives to see if anyone else has had
problems similar to mine, and found yours.  I was wondering if there
had been any further resolution since the last round of messages
circa 7-Jan-2001?

If not, perhaps my info will add some data for Gerard or others.

My story is that I just now began trying to move from 3.3 to 4.2
(because only 4.x can understand large ATA drives, sigh) and ran into
some odd error messages that look like this:

	sym0:0: message d sent on bad reselection.
	sym0:0:control msgout: 80 20 35 d.

I have a Tekram DC390-U2W and this problem is happening with a Conner
CFP1080S (Conner again... hmmm).  Tagged Queueing is enabled.  It
isn't frequent, but I haven't tried much yet.  Happened once during
shutdown for a reboot (which wedged things and required a fsck after
resetting the CPU), again upon logging in after a night of running
idle.  There are currently two other devices on the SCSI chain but
they should be completely unused (nothing is mounted from them).

I would have used the NCR driver, except I couldn't figure out how to
coerce the new 4.2 /usr/sbin/config to accept the setting of
SCSI_NCR_DFLT_SYNC=6 which is required in order to use LVD drives at
full 80Mb/s speed.  Grumble.  Different topic.  Was hoping SYM would work
without this fussing, but until I understand what's going on with "bad
reselection" I'm not going to put my LVD drives on this system.

Here's the dmesg since it always seems to be asked for.  Apologies if
it turns out to be unnecessary!
