Reproducing steps: can't reproduce
Dell Latitude N7110, nvidia card turned off with bbswitch.
On the laptop I had connected external monitor(with laptop screen active too).
Happened after system resume(was sleeping for ~3-4hours), then ~5-6mins of active work, and bam!!.
If it's not reproducible, there's not much we can do to debug it. Sorry.
Please test a new version of Mesa (12 or 13) and mark as REOPENED if it happens more frequently or if you discover a way to reproduce it.
This Mesa bug has been in the "NEEDINFO" status for over 60 days. I am closing this bug based on lack of response but feel free to reopen if resolution is still needed. Please ensure you're supplying the correct information as requested.
