I tried to revert my patch (commit 254c4407cb84a6dec90336054615b0f0e996bb7c)
but I'm still able to hit the very same kernel panic in linux-next, so I think
my patch is not the one to blame.

I was able to reproduce the error in a more easier way:
just execute the "reboot" command after the system boot is finished.

Regards,
Maurizio Lombardi
