I test the test kernel built by Koba, https://drive.google.com/drive/folders/10ns_2dnmPRf091L3LABpIh680kStvTk4?usp=sharing

sku: FPA-DVT2-C6
BIOS: 0.0.26

It still have the error in kernel, but the screen can show successfully. I tried pure 5.14.0-1011-oem, the issue is still reproduced. Therefore, I think the patch set indeed fix something, but it won't get rid off "kernel: i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun: soft,transcoder," however, my local build drmtip [1] can eliminate the error message.

@koba

Would you please check if it includes all required patch? Currently, we have some problem on other platform STRADL-DVT2-C4/C5B, it will cause it failed to suspend/resume.
