Subject: Bug: amdgpu stutter and spam `Fence fallback timer expired` after suspend
Date: Thu, 06 Jan 2022 00:26:15 +0300	[thread overview]
Message-ID: <7143a7147978f4104171072d9f5225d2ce355ec1.camel@yandex.ru> (raw)

Hello! Just a heads up to this report https://gitlab.freedesktop.org/drm/amd/-/issues/1850

Basically, after waking up on suspend there're freezes in apps using amdgpu, and there's a spam in syslog `Fence fallback timer expired on ring …`.

I bisected that to a commit 

	5a7b95fb993ec399c8a685552aa6a8fc995c40bd i2c: core: support bus regulator controlling in adapter

Since the commit is not in AMDGPU, I send this email to linux-i2c. The commit author CCed as well.

Should I send a revert, or is there a way to fix this?
