Lenovo X1 - kernel 6.0.N - complete freeze btrfs or i915 related

[Norbert Preining]

Hi all,

(please Cc)

I got a new laptop Lenovo X1 Gen 10 Alder Lake, and installed Arch on
it. In contrast to my desktop that runs the same kernel and software,

kernel 6.0.N (latest stable), with or without -zen changes
Arch linux uptodate
Hardware name: LENOVO 21CBCTO1WW/21CBCTO1WW, BIOS N3AET67W (1.32 ) 09/27/2022

The laptop is freezing like hell. At the moment it hangs reproducible
on every boot after a few seconds (around 20?).

I captured a call trace on photo:

btrfs_release_delayed_item.part
btrfs_delete_delayed_dir_index
...

(more on request, I can type it in)


Intel i915 also has loads of warnings. I tried with 
	i915.enable_psr=0
otherwise screen flickering and tearing is bad, and bad pixels show up.
Adding the enable_psr=0 did fix that.

Other things are that the GUI (Plasma via X11 - not wayland) is often
freezing completely. But I guess that is a consequence of the btrfs
error above, since starting new shell does not work, anything that wants
to read from disk is hanging.

I captured a recent boot log:
	https://www.preining.info/boot.log
which shows in detail hardware etc.

I am more than happy to:
- compile kernel with patches
- provide detailed information as far as I can gather them

Thanks for any comment/help

Best regards

Norbert
