We're also seeing a big increase in instability since moving to the
RHEL 6 kernels. Specifically, our typical platform consists of a
Supermicro motherboard with dual 12-core AMD procs (ie. 24 in one
system); The most frustrating part is that the symptom we're seeing
is highly intermittent (sometimes it takes 10 minutes to trigger,
sometimes several days), and doesn't result in a kernel panic or dump
per se. Instead what we're seeing is an unresponsive system (still
responding to ping, but all services on the box are unresponsive),
with this scrolling by on the console:

BUG: soft lockup - CPU#22 stuck for 67s! [node:585441]
BUG: soft lockup - CPU#23 stuck for 68s! [node:585419]

(multiple times per second, repeating all the different process
numbers and many different processes running within containers).

We're going to file a bug report on this, of course, but wondered if
there was anything else we can do here to get any other information
which can help the devs to come up with the cause and hopefully fix
for the above? (Again, we're not getting a panic, and we're not able
to do anything on the console.)

Thanks,
Stephen
