Subject: Adaptec 1542A Users
From: Julian H. Stacey <jhs@

If both of these are true for you:
 - Don't have login access on a system with an Adaptec 1542A SCSI Controller.
 - Aren't interested in scsi or kernel.
Save Time & SKIP THIS MAIL !
If only one line is true, or neither is true ... read on please :-)
(1542B-only-owners should  ignore this, I too have a B, & it shows no problems)

This is an Appeal For Email Addresses of the few remaining programmers who
have user access (root access un-necessary)
to systems with Adaptec 1542 A SCSI controllers, with at least
2 scsi disc drives, on FreeBSD-2.1 (ie CD release), stable, or current,
(2.0.5 & earlier probably also relevant)

I have found a bug, involving sd1 & sd2 & sd3 (but not sd0), asserting
8 * 0xFF at the beginning of random blocks aligned at 0x1000 intervals.
I want to clarify if it's a generic FreeBSD bug or unique to my card.

I have written a smallish testblock.c & .man I would like to send you,
that runs in user mode (no root access or S bits or access to devices required),
it's well behaved & writes a test pattern to a normal file,
I would like you to mail me resulting error messages if any.

Volunteers can be assured it's only 5 minutes work to run the test prog, it
won't zap your disk, & it may catch a nasty bug you didn't even know you had :-)

Please email me your names privately, without bothering to CC lists.  Thanks !
(PS apologies for having dual posted current & hackers,
but I need the non overlapping subsets).

Julian
