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

Hello

Just for the record, I'm seeing the same issue when running a Debian 
image with 4.12 in a VM.

If I don't switch away from plymouth and to the text console under boot, 
the whole system freeze.


I manged to get this log, by starting plymouthd manually after boot:

plymouthd --debug --debug-file=/tmp/f --tty=/dev/tty2 --mode=boot 
--kernel-command-line="quiet splash"

plymouth show-splash

The whole system is frozen, but I still have ssh access.
