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). -- Meelis Roos (mroos@linux.ee)
