Any suggestions on how to resolve? Should one expect robust mutexsupport?
There was a patch to support for robust futexes on SMP kernel last year, from Anton Vorontsov:

There was some discussion on this patch, but I think the work was never completed to address the concerns.
Maybe you were running with this patch at an earlier time?
The patch was waiting for Catalin Marinas' "Remove the domain switching on ARMv6k/v7 CPUs" patch to hit Linus' tree. Now that the patch is in, the robust mutex support should be OK with the patch above (but a minor change[1] would be needed to get it into mainline).
Thanks,
