kern/114597: System hangs at SCSI bus reset with dual HBAs

[mjacob at freebsd.org]

Yuu're missing some info:

What kind of Symbios in all of the systems?
Which architecture? i386 I would guess, but pls confirm
You say 7.0 current in summary, but then say 6.x/7.x. Can you confirm 
*any* 6.x release working for you?
