Ok,
btw, here might be another path which hits this (at least I think so).
http://alt.swiecki.net/linux_kernel/sys_mprotect-2.6.38.txt
And, generally: here are a few deadlocks/bug_on's/ooops gathered earlier (some fixed already) - http://alt.swiecki.net/linux_kernel/ - I'll try to ask for fixes for them one by one, as soon as they repeat and I have proper kdb/perf dumps.
