Ben, I cannot reproduce the crash with 3.7-rc4, I spotted commits
a7dbf00 and 5cad16a which seem to be related to the problem I was
having; would you mind elaborating a bit about what you think was
causing the crash on my side? Maybe the chipset used on this motherboard
doesn't support some feature? And how did you figured out from the logs?

Thanks,
   Antonio
