Not really - everything's tangled up.  A bisection search on the
2.6.21-rc7-mm2 driver tree would be the best bet.

And the winner is:

gregkh-driver-driver-core-make-uevent-environment-available-in-uevent-file.patch

Reverting only that from 2.6.21-rc7-mm2 gives me a working kernel
again.

I'll try building 2.6.21-git3 minus that one next, but I'll have
to revert it manually, because my naive attempt to "patch -R" it
failed 1 out of 2 hunks.

Ok, that's just wierd, it only adds a new feature, it doesn't touch any
existing code to cause things to go wrong.

Can you try using 'git bisect' on Linus's tree instead?  That should
show the real problem much easier.

thanks,
