Yes, but does it lock up the drive?  Or just a cosmetic problem..  We add
quirks for the drives that crash or lock up if I recall correctly.  (I have
one of these drives too <CONNER CFP2105S  2.14GB 2D4D>, it complains too
but doesn't fail).

Cheers,

Instead of quirking it, can you try the attached patch?  Justin and I have
a theory on why these messages might be popping up, but we're not quite
sure.

I've tested this under -current, but the patch is against -stable, which
should apply okay to your 3.4-RELEASE sources.  (Obviously, you'll need to
remove or comment out your quirk to test this.)

Anyway, let us know how it works.  Make sure to CC your mail to
FreeBSD-gnats-submit@FreeBSD.ORG, so it gets in the log for this PR as
well.

Thanks,

Ken

I see the same error message on my system after I 'shutdown', then 'halt'.
I have two disks on the scsi bus, but it only complains about da0.  (I see
the _exact_ same error message as above).

I applied your patch, but still see the same message. (exactly the same)

What I noticed though, because my da0 (100MB) is totaly dedicated to swap,
if I boot single-user without executing 'swapon', it would not show the
message during reboot.  I can read/write _just_ da1, then reboot, and no
message.  If I do a 'swapon' in single-user mode, I see the error message
after 'halt'ing.

In other words, if the controller does not access da0, I will not see a
message.
