Sorry about that. I didn't notice any issues with the same testing
procedure that easily reproduced issues without the revert, so I thought
it should be at least an improvement.

Anyway, with this patch, the attached warning dumps appear in dmesg
about 1000 times per second at the GDM login prompt, can't even attempt
