How reproducible is the crash? What previous kernel was known to work? Can you narrow it down to a particular revision, preferably with kernel debugging enabled? (see the end of the mail) There was one invasive change merged - fine-grained namecache in r310959 and that can be treated as the likely culprit. That said, I would start the search with verifying there are no issues with r310953 first.
