That one commit being

commit 7d9a74622e5a936e4860fcef8358619bf59adae8

    sna: Be robust in handling DPMS failures

i.e. not a kernel commit. Apparently Chris' conclusion was that the kernel
returns an error on DPMS.

Please attach dmesg with drm.debug=14 module parameter, all the way from boot
to reproducing the problem.
