The md code had significant changes in either 2.4.19 or 2.4.20 (I
forget which, sorry). I'm running RAID over LVM on a sun4u here on
2.4.20 with no difficulty. 2.4.18 would freak out regularly with the
same setup; I wasted an entire night fighting with it.

How have you set up SILO? I used a non-RAID /boot as you can see.
I'm interested in other approaches.

For myself, I can only say that I am astonished and somewhat terrified at
the results of this evening's experiments. Astonished at the wonderful
power you have developed, and terrified at the thought that so much hideous
and bad music may be put on record forever.
