I got this Asus Zenbook s14 laptop a few months ago and after the initial setup and updates I switched to linux.
In the beginning everything was great but since ~November 2025 I started experiencing random total system freezes/stutters.
I couldn’t find a pattern but I can replicate it mostly after the laptop is being used and then left to idle for like 30 sec. Then I get a total system freeze and the screen dims. It’s stalling and stuttering intermittently for about a minute after which everything goes back to normal for a while.
I am now on Omarchy and it’s still happening. Btop shows a process called btrfs-cl spike during the freezes. It spikes as high as 12-13% CPU usage, sometimes draining considerate amounts of battery and heating up to the point it starts the fans.
I tried both i915 and XE drivers, happens with both. I am on Kernel 6.18.6 now.
I just got my first total system freeze that was unrecoverable and I had to hard reboot.
Not sure if btrfs is the cause of the issue but I did ran a journalctl and this is what i found.
Can you interpret/advise, these are too technical for me.
These do not appear to be the logs of a total system freeze. Although i do like you including the timestamps here. normally logs are in seconds since boot and i have to do math in my head.
Can you get the logs from immidiatley after one of these freeze events?
what is home1.service? ive never heard of that. looks very spooky
looks like youve got some malicious software running. as the x86 perf bias got changed from performance to normal, usually you always want it set to performance and just allow acpi cpufreq or intel pstate to throttle up and down as needed for battery efficiency.
Omarchy has this thing to manually adjust power profiles. Also it automatically switches to performance when plugged in and then power saving when unplugged but I manually switch to Balanced. I don’t know what home1.service is.
But this looks like an issue of compatibility of the kernel with the Lunar Lake platform. Probably you upgraded a kernel version in november that had some regression?
