Similar error happened also on guado, buddy and peach_pi.

Taking a look. Thank you.

I started to test IMPORT mode from 10117.0.0. https://chromium-review.googlesource.com/c/1186391/

All the failures happens in IMPORT mode. I suspect these failures. Would you annotate this failure? I will run for fix next week.

Okay, I'll annotate these devices.

For nyan_big, it started to fail on R70-11017.0.0
https://crosland.corp.google.com/log/11016.0.0..11017.0.0
Chrome version not changed.

Same for guado, buddy and peach_pi. Suspect culprit in kernel.

Hiro, you may be right. I'll confirm it later tonight.

Confirmed that the culprit is https://chromium-review.googlesource.com/c/1186391/

Hiro, shall we revert it first?

I reverted the CL crrev.com/c/1200542.
It was landed at M71. So I need to cherry-pick to M70 to resolve the failures at M70.

Your change meets the bar and is auto-approved for M70. Please go ahead and merge the CL to branch 3538 manually. Please contact milestone owner if you have questions.

I reverted it at M70 too. So no failure will happen.
