Bug ID: 209713 Summary: amdgpu drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_l ink_encoder.c:483 dcn10_get_dig_frontend+0x9e/0xc0 [amdgpu] when resuming from S3 state Product: Drivers Version: 2.5 Kernel Version: 5.8.13-arch1-1 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: samy@lahfa.xyz Regression: No
Created attachment 293025 --> https://bugzilla.kernel.org/attachment.cgi?id=293025&action=edit parts of dmesg where the call trace happens during the resume from S3 sleep state.
I'm thinking that this bug is a regression since I haven't seen this call trace before on kernel older than 5.8.12-arch1-1 but I have yet to confirm this.
The call trace may also happen only in a very specific way, my current computer has a USB-C Dock that is plugged in and the call trace happened when the USB-C was plugged in and the computer was suspended, then resumed.
It is a Lenovo Thinkpad T495 model 20NKS28F00 with an AMD Ryzen 7 3700U and a Vega Radeon RX 10.
Further comments will confirm if the call trace happens only when the USB-C Dock is plugged.
As well as if this call trace happens on kernels older than 5.8.12-arch1-1.
The computer does resume successfully and there is a like a minor screen glitch for a millisecond so it's not a very severe bug.
