Even with the latest patch applied (https://bugs.freedesktop.org/attachment.cgi?id=97193) the problem still occurs.
The system does recover from the reset faster than before though - suspends and resumes in a few seconds now, whereas earlier it would take a few tens of seconds to snap out of the reset cycle.
Please attach your dmesg output with the patch applied. It shouldn't try and auto suspend or reset the integrated card at all. Somehow it seems like runtime pm is still getting applied to the integrated card.
