I've got an Intel(R) Iris(TM) Pro Graphics 5200 ( in a Macbook ), and I'm running a 4.1.5 *vanilla* kernel, libdrm-2.4.64 and mesa-11.0.0.
I get occasional hangs in X, lasting for about 5 seconds each, where the display stops updating ( other than the mouse ). Everything else appears to continue - eg music continues to play, input continues to be accepted.
These hangs occur in pairs, eg hang => working ==> hang ==> working, and these pairs occur maybe once every 4 hours or so.
I had previously been using an RT kernel, but have moved back to a vanilla kernel to test this issue ( which does occur in the vanilla version ).

The dmesg output ( attached ) was taken *immediately* after such a pair of hangs ...
After a hang do:
If there is one:
'cat /sys/class/drm/card0/error | bzip2 >error_state.bz2'
And attach to this bug. Thanks
Thanks for the response. 'cat /sys/class/drm/card0/error' gives:
no error state collected
I assume then that this problem is *not* in the driver, and probably in Enlightenment.
I'm happy for you to close this bug.
Ah I see I can close bugs. Setting status 'NOTOURBUG'.
