So I'm giving up on mdadm/RAID1/WD10EARS Green Drive experiment for
the next day or two. I've tried 4 times in the last two days to see if
I can get this machine to boot using RAID. I keep running into crashes
that look like the one below. I will try a non-RAID install and see if
the hardware is stable and then come back to this later if
appropriate.

I was running a March, 2010 Gentoo install CD when this happened. One
terminal doing bash completion of all things was hung with 1 CPU stuck
in a 100% wait condition. New terminals continued to work if I didn't
try to access the hard drive. I can run things from the CD.

I have never seen a Gentoo install use nearly 2GB so something is
really going wrong here.

Cheers,
Mark
