Tried it on Netra X1, Ultra 2 and V100 that were online (applied the 
patches and enabled THP with defaulting to always).

Ultra 2 did not boot up (will see on Monday).

Netra X1 performed a simple dist-upgrade fine with this kernel.

V100 boots up fine but as soon as I start aptitude, it just hangs with 
nothing on console (tried it twice).
