Subject2.6.33-rc1: WARNING: at kernel/mutex-debug.c:78 (geode hw rng?)
Hi,

not so sure if it is geode related.
While starting rngd on 2.6.33-rc1 on a geode machine, I got this warning:

[ 19.545852] ------------[ cut here ]------------

however, the system seems stable, and the hwrng seems to work fine...

Best regards,
