[snip card dump/dmesg WHY]

[Late I know but...] 
Looks like this is still broken.

I have Adaptec 29320 plus four Seagate Cheetah ST336607LW (firmware 0006 = 
latest).

4_8 dies during the SCSI neg, 20030731-JPSNAP boots okay. This is a 
replacement setup for my works firewall. It dies during restore. Tags level 
was 33 post card dump so the camcontrol "fix" will probably work.

Don't have an analyzer, but I can do some of the legwork if someone will "hold 
my hand". Pending MFCs?

The existing drives are running on borrowed time so I'll have to put the new 
drives into production next week.

CC me if I can help.
