Hi,

Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated
to http://gitlab.freedesktop.org.

To avoid migrating out of date bugs, I am now closing all the bugs that did not
see any activity in the past year. If the issue is still happening, please
create a new bug in the relevant project at https://gitlab.freedesktop.org/drm
(use misc by default).

Sorry about the noise!
