Comment 1 Josh Boyer 2012-04-20 12:40:59 UTC

Please try the 3.3.2 kernel update.

Comment 2 Mohammed Shafi 2012-04-23 16:11:52 UTC

looks same as
https://bugzilla.redhat.com/show_bug.cgi?id=811142

in the above bug,
i had asked for debug logs, though the lock up seems to be fixed ,while there are some other functionality issues.
need to take a look at the code , as i was out of station for some days.
also need to recreate the issue here
