in case it's helpful, there's supposed to be a 2.6.21 backport in 
backports.org, but there was a problem with the arm upload or something to 
that effect.  i've spoken with the arm/bpo buildd admin (kmuto) and he's 
going to fix the problem soon.

looking in upstream git, i can't be sure but i think this might be the fix:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=da6e1a32fb8d7539a27f699c8671f64d7fefd0cc

or at least the BUG_ON is right about where i saw it (give or take a few 
lines). 

i don't really have the resources to try compilingpatched arm kernels,  but if 
you do and want me to test something just let me know.
