Hi all! I have a Lenovo Thinkpad X1 Carbon Gen 8 that I installed Arch on following this guide - https://github.com/joelmathewthomas/arc … me-ov-file - to get an install where I had LVM on LUKS with Secure Boot and TPM unlocking and a swap partition so I could hibernate the laptop.
Unfortunately, I'm seeing occasional and not-clearly-reproducible freezes and or kernel panics (e.g. Caps Locks starts to blink).
Looking at `journalctl -xb -1` after this happens doesn't have any clear pointers; I suspect that journal isn't being written to disk before the panic.
I'm running with systemd.journald.forward_to_console=1 console=tty1 in my kernel command line to get additional debugging to console but I'm not sure where that information will print and if journalctl will capture them?
Hardware tests (Lenovo's UEFI diagnostics; memtest86+) don't show any hardware errors. Also other distros (e.g. ubuntu) don't seem to exhibit this issue.
I thought about installing kdumpst to try and get kernel dumps on panics ... but my install means that I can't run grub as it doesn't support LUKS2.
Wanted to see if given this setup, there was a recommended path to either a) resolve this; b) gather further debug info to try and diagnose this issue.
Thanks!

After a solid 36 hours just had a freeze, journalctl -xb -1 had the following:

Just hit this again even with i915.enable_dc=0 as a kernel command line parameter.

If you are adamant on using arch and ubuntu 24.04 doesn't crash then maybe downgrade the kernel to the one ubuntu uses 6.8.x.
You need to install an RTFM interface.
