Per https://bugzilla.redhat.com/show_bug.cgi?id=477671#c37 John, suggest you try this TEST KERNEL and report results back here. Setting bug to NEEDINFO walicki.com
Thanks Larry - I have sent this kernel to my IBM test team and to some IBMers who are affected. Will report back on Monday.
We'll have more feedback from IBM users on Monday but I've received confirmation from one user who is now running the new kernel without the 'options iwlagn 11n_disable=1' modprob.conf param. He is not getting the same kernel panic at boot time anymore. Things are looking very promising. Thanks
