After analyzing the kernel commits around the problematic firmware version (0.27.97.0), I’ve found some interesting changes in power management and firmware handling that might be related to the stuttering:
- Changes in how power modes are handled during WoWLAN states
- Different interrupt handling during firmware operations
- A reversion of firmware format from version 1 back to version 0 in the kernel code
I’m currently testing a minimal configuration that disables power saving features:
/etc/modprobe.d/rtw89.conf:
options rtw89_core disable_ps_mode=Y
Initial testing has shown mixed results - some boots work perfectly while others still experience stuttering.
If anyone wants to try this configuration:
- Create the config file
- Run
sudo dracut --force - Reboot your system
Would appreciate if others could test and share their results, particularly noting if they experience inconsistent behavior between reboots like I have.
