That's not an oops, that's a WARN_ON.  The hardware wasn't caught up by
the time we gave up when shutting down the harwdare for VT switching.
That's bad.  But we don't know how long we should wait, since the GPU
may be hung, and waiting forever would be bad.  So we warn that
Something Bad may have happened.

It's gone with KMS since we never shut down the GPU.
