<pre>We can find a good commit.
Kernel: (drm-intel-nightly)cdb96764a45f87e4614df1b16d68b2ccb9806f57 good
Kernel: (drm-intel-nightly)071f0a705c081ed6b1d61b6fa8be969a5b15ddf8 bad
But now the good commit"cdb96764a45f87e4614df1b16d68b2ccb9806f57" can't find in
the branch drm-intel-nightly any more.
With the latest kernel, the issue still can be reproduced. But if adding
"drm.debug=0xe" in kernel command line, this issue can't be reproduced.
