Description Adam Mariš 2016-11-18 22:42:21 UTC 
The fimg2d which is one of the graphic devices for Exynos chipsets doesn’t have exception control routines to handle unexpected commands and it can lead to kernel panic. The patch prevents kernel panic by ignoring inappropriate commands at the state.

Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1396671]
Comment 2 Justin M. Forbes 2016-11-21 17:43:45 UTC 
Not sure why we have a bug on this, the driver in question is in an upstream android tree at google, but not in Linus' linux kernel tree. Fedora doesn't ship this driver.
Comment 3 Wade Mealing 2016-11-28 05:47:11 UTC 
Righto, will close that up.  There was enough CONFIG_EXYNO in the fedora kernels that it was affected.
