As I mentioned in my previous post, Ubuntu recently released a 3.11.0 kernel for Precise. Unfortunately, while it appeared stable during a long burn-in process with various pgbench workloads and scale sizes, it crashed shortly after putting the machine into service, so make sure you test thoroughly on your hardware.
This particular hardware was the Dell Poweredge 720 that rackspace uses.
Guess we're going back to custom compiling kernels for a little while longer.
Anyone else have experiences good or bad with it?
I believe this is the same kernel that's shipping with 13.10 Saucy Salamander.
