Subject: Re: 2.6.20.7 locking up hard on boot

I can confirm that reverting commit
7639e962234c76031d1ddf436def7fd9602be560 fixes the problem.  Also,
there seem to be plenty of other people reporting the same boot
locking:

Please consider reverting this patch in upstream.
Thank you for your time,
Marcos
