It seems to work ok for me, but it causes quite a few new warnings on
my Sony VAIO Pro laptop. It's (once more) a regular i5-4200U CPU (aka
Haswell, aka 4th gen Intel Core i5)
Most of them are in check_crtc_state(), and I currently have 18 of
these in my log:
[drm:check_crtc_state [i915]] *ERROR* mismatch in
dpll_hw_state.wrpll (expected 0x90280202, found 0x00000000)
WARNING: CPU: 0 PID: 115 at
pipe state doesn't match!
but there's a few others too:
WARNING: CPU: 3 PID: 1871 at
plane A assertion failure (expected on, current off)
WARNING: CPU: 3 PID: 1871 at drivers/gpu/drm/drm_irq.c:1162
vblank not available on crtc 0, ret=-22
and the backtraces aren't all that interesting, but I'm attaching the
cleaned-up dmesg, duplicate callchains and all.
