Thanks for the core dump and bt Christophe. After a bit of research, I believe this is a race condition present in 2.4.7 which was subsequently patched, and then the patch refactored when the suspend/resume hooks were added in 2.4.10. The fix in 2.4.7 seems simply enough (just move c->sbh = NULL into the suspend condition above it) but I don't think it would pass SRU justification since it only happens under load and is hard to reproduce. Can you and/or Ian use 2.4.10 from trusty-backports? That shouldn't suffer from this problem.

If not, reply here and I'll get someone to validate my SRU opinion before proceeding.
