Ensel,

I chatted with Scott a day or two ago, and he told me he believes he has 
tracked down a bug in the adaptec device driver under high I/O load, and 
thinks it is possible that quotas are triggering slightly higher load 
resulting in the bug being exercised.  He has a patch, which hopefully he has 
now sent to you?
