QXL hang with 4.12.0 kernel ("kernel BUG at drivers/gpu/drm/ttm/ttm_bo_util.c:589!")

Wed Jul 19 05:14:48 UTC 2017

Hello,

As requested in https://bugs.freedesktop.org/show_bug.cgi?id=100725,
I'm attaching a log with details concerning a freeze relating to the
QXL driver that I'm encountering with the 4.12 kernel for i386. (Note
in order to duplicate this, a graphical boot option must be enabled. In
my case, I'm testing in a Fedora environment, so I have "rhgb quiet"
as boot parameters, along with "drm.debug=0xe" in this example. I'm
not able to reproduce this with a text mode boot.)

Regards,

Dave
