Damn. I read about this in the LWN.net Kernel pages for may 17th. I
figured that once it was in, everything would automagically be using it
too (i.e. the drivers wouldn't need to be updated to the new system).
Guess I was a tad naïve about that.
I tried 2.6.17-rc5-mm2 and ran into some BUG()s which went away when I
just stuck to 2.6.17-rc5.

Looks like a good idea, thanks!
Don't let that keep anybody on this list who might have an explanation
for this be deterred from responding though. :)

I've been sitting on a non-functional array for almost 3 months now.
Don't mind having weird issues a little longer if it means things will
end up working nicely in the end (or I at least get a sensible
explanation for what's wrong, so I know what I must do to fix it).

Kind regards,
