Hi David, others
Results seem OK
recap: I have 2 6core 64bit opterons and I make -j13

Hi all
If someone can provide the patches (or learn me how to get them with
git (I apologise to not be git savy)) then, this weekend, I can apply
them to 3.6.6 and compare before/after to check if they fix #49361.
Thanks

Hmm, interesting since there are no core VM changes between 3.6.2, the
kernel you ran into problems with, and 3.6.6.
Hi all, please let me know if there is are patches you want me to try.
FWIW time did not stand still and I run 3.6.6 now.

Hmm, interesting since there are no core VM changes between 3.6.2, the
kernel you ran into problems with, and 3.6.6.
