linux-zen 5.19.12.zen1-1 makes my laptop unusable [5.19.13 fixes it!]

I did an upgrade and a reboot.
External monitor, ethernet, keyboard and mouse are attached to an external USB docking station.
My laptop screen went black while back-light started flickering.
Second screen was OK, but mouse wasn't working.
I did a CTRL+ALT+F2 and switched back to previous version linux-zen 5.19.11.zen1-1 while ignoring linux-zen packages from upgrades.
Everything now works.
I am available to collect logs and other details once my working day is over.

[UPDATE]
5.19.13 works just fine!

Re: linux-zen 5.19.12.zen1-1 makes my laptop unusable [5.19.13 fixes it!]

FWIW, I have a very similar setup here (docking station and all) and haven't had any issues with 5.9.12.zen1-1.  No chance that it's something as simple as a loose cable?

No way!
1. Laptop screen stops working
2. If I downgrade I fix it. If I re-upgrade I break it.
No loose cables here, though.

Same issue here with both standard Arch Linux kernel as well as Xanmod. Upgrade from 5.19.11 to 5.19.12 breaks video on Intel graphics (11gen).

Re: linux-zen 5.19.12.zen1-1 makes my laptop unusable [5.19.13 fixes it!]

@smn can you bisect between the two releases and identify the causal commit?
Edit:
Please try the kernel linked below which is 5.19.12 without any additional locally applied commits

Re: linux-zen 5.19.12.zen1-1 makes my laptop unusable [5.19.13 fixes it!]

I have the same issue after upgrading to linux-zen 5.19.12 today.

After I upgraded I rebooted. Instead of grub I saw flickering.
I booted via usb stick and set GRUB_GFXMODE from "auto" to "640x480".
On the next boot grub menu appeared and flickering started after selecting linux-zen boot entry.

I tried an older kernel (bcachefs-simple-git with base 5.19 that I compiled last week) and everything works.

I tried both kernels that @loqs provided in the previous post and both have the issue.

edit: I forgot to mention that I also commented GRUB_GFXPAYLOAD_LINUX=keep so that grub resolution is not kept. I haven't tried with this active. I have not changed this setting since.
edit2: Sorry, i just looked at the build date of the working kernel and it is 2022-08-26, so more like 4 weeks ago. I compiled that kernel last week but did not install it on this machine.
edit3: Sorry again, this time for all the edits.. I am on 12th gen intel graphics here

Re: linux-zen 5.19.12.zen1-1 makes my laptop unusable [5.19.13 fixes it!]

I can confirm the behavior on a machine with intel graphics 11th gen.
When I shutdown with the faulty kernel 5.19.12, a call trace is displayed.
Don't know if I can find it in any log to post it.
But the last lines are:

[...] i915 ...: [drm] *ERROR* [CRTC:...:pipe A] flip_done timed out
[...] i915 ...: [drm] *ERROR* [CRTC:...:pipe B] flip_done timed out

Re: linux-zen 5.19.12.zen1-1 makes my laptop unusable [5.19.13 fixes it!]

@loqs I tried this kernel and it also results in flickering

Since I buried this info in an edit and it might be important, I want to restate that I am running 12th gen intel graphics
And also that grub was showing this flickering behaviour too (which I find surprising - did not know there was a connection betwenn kernel updates and grub - at least in this way)

Re: linux-zen 5.19.12.zen1-1 makes my laptop unusable [5.19.13 fixes it!]

both show the flickering

the only difference in all these tries, was with r52 and r26 I too got the stack trace mentioned earlier, but not reproducible (at least not on the next try)

    drm/i915/bios: Split VBT data into per-panel vs. global parts
    
    [ Upstream commit 3cf050762534cc268a02793ec00240f81c6e2229 ]
    
    Move the panel specific VBT parsing to happen during the
    output probing stage. Needs to be done because the VBT
    parsing will need to look at the EDID to determine
    the correct panel_type on some machines.
    
    We split the parsed VBT data (i915->vbt) along the same
    boundary. For the moment we just hoist all the panel
    specific stuff into connector->panel.vbt since that seems
    like the most convenient place for eg. the backlight code.
    
    Note that we simply drop the drrs type check from
    intel_drrs_frontbuffer_update() since that operates on the whole
    device rather than a specific connector/encoder. But the check
    was just a micro optimization so removing it doesn't actually
    mattter for correctness.
    
    TODO: Lot's of cleanup to be done in the future. Eg. most of
    the DSI stuff could probably be eliminated entirely and just
    parsed on demand during DSI init.
    
    v2: Note the intel_drrs_frontbuffer_update() change
