2.6.32.x is still the recommended branch since it is the stable
maintained branch. 2.6.37+ are currently development branches. So we
really ought to try and get to the bottom of your issue.

Which exact kernel version (git sha1) are you using?

http://wiki.xen.org/xenwiki/XenParavirtOps contains (under "Are there
more debugging options I could enable to troubleshoot problems with Xen
and/or dom0 kernel?") further details of useful debugging options to
use.

Please can you try converting the various addresses from your stack
trace into functions / line numbers. I usually use "$ gdb vmlinux" and
then "(gdb) list *0xaddress", other people use addr2line, both options
require that you have a kernel built with debug symbols
(CONFIG_DEBUG_INFO IIRC).

Ian.
