FP3 logcat spammed (9 per second) with: HWPrimary::SetRefreshRate: Failed to open /sys/devices/virtual/graphics/fb0/dynamic_fps

• /e/OS version: 2.9 (at least present since 2.8)
• Device model(s): FP3(+)
• Impacted Application: logcat

The problem

logcat is spammed with the following message. About 9 occurrences per per second on an idle device.

05-13 01:24:10.366   543   543 E SDM     : HWPrimary::SetRefreshRate: Failed to open /sys/devices/virtual/graphics/fb0/dynamic_fps with error No such file or directory

 

UPDATE: Duplicate #8224 (closed)
Seems there may be a LineageOS fix which could be cherry-picked.
Can I somehow make a pull request? Seems I can't clone the android_kernel_fairphone_FP3 repo to make a pull request, because this GitLab instance tells me:
You cannot create projects in your personal namespace. Contact your GitLab administrator.

 

Steps to reproduce

1. installed IMG-e-2.9-t-20250321478215-official-FP3.zip, including wiping the device.
2. do the initial setup with default values, skip whatever is possible (no WLAN configured, ...)
3. open system settings to enable developer mode, USB debugging and root debugging
4. connect a PC via USB and run adb shell logcat
5. don't let the phone's screen turn off
