Does this only occur on a Nexus 5 or also a flame now?

Also, does this happen on master or only 2.2?

I see that error for CPUs 1-3.

This looks more like a hardware composer issue on L than anything with the vsync refresh driver. There looks like a potential race condition issue with enabling vsync and something in the gonk layer. Disable the vsync refresh driver on L until we sort out the hardware composer issues.

@Jerry - Can you please work with Hermes who also resides in Taipei to take a look at this? I don't have a Nexus 5 device. If you can't make progress on this, I can get a Nexus 5.

I will check this issue.

This error message is weird. The ioctl write a cmd to device at , and the device node("/dev/graphics/fb0") already exists. Diego, do you know why we got this error? E/qdhwcomposer( 190): hwc_vsync_control: vsync control failed. Dpy=0, enable=1 : Operation not supported on transport endpoint  http://androidxref.com/5.1.0_r1/xref/hardware/qcom/display/msm8974/libhwcomposer/hwc_vsync.cpp#44
I turn on the vsync-rd with today's m-c build, but I don't get this issue. Still investigating.
I'd rather have a separate bug filed for disabling vsync refresh driver on L, as it will be easy to track since this bug is still going to be open to track the original issue with vsync refresh on. For now, to unblock qa approving the patch and adding check-in needed.

Considering the disabling patch already landed as part of this bug it seems simpler to close this bug and do the work to re-enable it in a new bug.
Please don't set checkin-needed on uplifts unless the bug only affects the branch and not master.
NI myself for following verification
