Okay you don't really want to use udl devices as your console, but if you are unlucky enough to do so, you run into a lot of schedule while atomic due to printk being called from all sorts of funky places. So check if we are in an atomic context, and queue the damage for later, the next printk should cause it to appear. This isn't ideal, but it is simple, and seems to work okay in my testing here. (dirty area idea came from xenfb) fixes a bunch of sleeping while atomic issues running fbcon on udl devices. Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com> |
