Great, I'll take a look for it tomorrow morning if I'm lucky.

Hmmm... I could have sworn that Neil sent a RAID1 patch out as well,
which was just adding an 'else' after a block. Here it is:

I've got a dual PIII 550 with 8 disks on it, so I'll see about beating
on it if I get a change. I need to take a backup anyway this
weekend...

The mdadm is alot better than the old raid stuff for sure.

Once I get 2.5.70* up and running, I'll try out my hacks to the
Cyclades driver (and we need a patch for the Kconfig entry as well,
it's wrong in it's description) under ISA to see if I can get it
working. I'll bounce those to you and Linus if they fly.

Thanks,
