this is followed by a GPU hang, but the mesa I have right now is based on 10.3.2 so could be due to that

It's a BIOS bug that got fixed at some point. So you should be looking for a more recent BIOS. Also see bug 84903, comment 8
Comment 2 Timo Aaltonen 2015-01-14 21:26:30 UTC
Right, well it would be great if premier.intel.com had anything newer to offer.. Anyway, I'll just wait.
