[Users] Is there a stable OpenVZ kernel, and which should be fit for production

[Stephen Balukoff]

Ok, y'all:

We managed to get a call trace.  I've opened the following bug on this
issue:  http://bugzilla.openvz.org/show_bug.cgi?id=2110

Anything else I can do or provide to get traction on getting a
developer to look at this?  (This is a complete show-stopper for our
Scientific Linux 6.1 OpenVZ roll-out.)
