dump card state begins...

[Jeffery G. Archambeau]

This particular box has been up and running without incident for a 
couple of years, now. It's running 6.2-RELEASE-p7 with the on-board 
Adaptec scsi controller.

This morning, the box was painfully slow. top shows that nothing's 
hogging CPU or RAM. bandwidth monitors show that the box isn't being 
attacked. Then dmesg showed this.... Help?
