I've just upgraded a machine from 2.1.7.1 to 2.2-STABLE
( up to ctm level 224 ) - I've been getting some nasty
SCSI damage. Here is the most recent hang - the lines
may be a bit messed up 'cos the machine hung again while
I was writing this mail, and I had to use the scroll back
buffer to get them.

The machine has 2 2940's, on the first one there is a
CD Rom, and 2 connor file pro's. On the second is a
conor file pro, and a Quantum Atlas. I've upgraded
the firmware on the atlas incase that is the problem,
but it still fell over.

TAGed stuff is off. I've tried MEMIO both on and off,
and neither seems to solve the problem. 

I'm going to try the 2 new CTM patches next.

	David.
