Re: Complete total freeze since 6.15 kernel

Hi everyone!

Apologies for being inactive - I’ve been away from my desktop for a while. Unfortunately, the system freezes are still occurring.
The freezes happen so abruptly that the system doesn’t log any errors - nothing shows up in journalctl or dmesg. My current suspicion is that newer kernels (post-6.15) might be handling power management in a way that conflicts with my RX 7900 XTX GPU.

To test this, I swapped in my backup RX 7700 XT, and the system has been running flawlessly - no freezes at all. So this issue might be specific to the 7900 XTX for some reason.

Re: Complete total freeze since 6.15 kernel

Hey @klutzer

Yes, the freezing is gone after I upgraded to 6.15.6. I have a session up for more than 10 days now using kernel 6.15.6 and no issues.

Re: Complete total freeze since 6.15 kernel

I have the same issue on cachyos, the only kernel thats completely stable with no freezes is 6.12.36-2-cachyos-lts
https://discuss.cachyos.org/t/freezing- … s/12462/16 Discussion post I made there with logs, seen the same issue on fedora, and i personally experienced the same issue on endeavour (arch) and Mint.  6850mxt and ryzen 6900hx

Re: Complete total freeze since 6.15 kernel

Ill get a stutter than a total freeze requiring a manual restart using the power button, nothing else will work.   On both gnome and kde, tried them both and reinstalling.

Re: Complete total freeze since 6.15 kernel

It seems to be fixed since 6.15.9-2 for me. At least after upgrading to that version (and versions above), I didn’t get any complete freezing anymore.

Re: Complete total freeze since 6.15 kernel

Hi everyone! It's been a while.

The issue is still there, even in the 6.18 kernel. However, I've managed to get a somewhat okay solution that works for me. I've also found a way to consistently trigger this issue: all I need to do is change the minimum VRAM clock in LACT. This most likely triggers the real issue (whatever it might be) rather than being the issue itself.

Now, for the "solution". There are two main things that work for me:

1. Use an LTS kernel (or any kernel before 6.15);

2. Configure GPU usage in LACT and system power consumption so the GPU never falls to the default "idle power-saving" state.

The configuration in LACT that works for me (contents of the configuration json file):

{"gpus":{"1002:744C-1458:240E-0000:03:00.0":{"fan_control_enabled":true,"fan_control_settings":{"mode":"curve","static_speed":0.5,"temperature_key":"edge","interval_ms":500,"curve":{"40":0.3,"50":0.35,"60":0.6,"70":0.9,"80":1.0},"spindown_delay_ms":5000,"change_threshold":2},"pmfw_options":{"zero_rpm":true},"power_cap":340.0,"performance_level":"manual","min_core_clock":790,"max_core_clock":3000,"max_memory_clock":1350,"voltage_offset":-50,"power_profile_mode_index":1,"power_states":{"core_clock":[0,2],"memory_clock":[1,2,3]}}}}

The system is set up to suspend after 1 minute of inactivity.
