Yes, I've been fuzzing this for a few hours on both my haswell and core2
test systems and it's doing great, also survived a reboot cycle.
Tested-by: Vince Weaver <vincent.weaver@maine.edu>
(Although often things like to crash the instant my tested-by e-mails
clear the lkml list.)
I also want to say thanks for all the work everyone has done in getting
this analyzed and fixed.
Vince
