Adaptec SCSI going nuts

[Joshua Coombs]

Just got a dual Opteron system to play with amd64 builds of FreeBSD. 
Poking around to see how it behaived, I initially tossed FreeBSD 4.11 
on it, and was surprised to see a dump of the scsi controller state at 
the end of the dmesg.  Tried 6.0-Rel, both x86 and amd64, same 
behavior.  Bumped up to 6-stable from yesterday, same behavior.  After 
the dump, the system appears solid, no other errors, so I'm guessing 
it's just a problem with how the card is initialized, FreeBSD corrects 
it and moves on.

Should I be more concerned, or consider it a quirk of the machine?
