Laptop unexpectedly hangs, only hard-reset helps

Hi, I have the laptop:

The kernel version:

uname -r

6.6.2-arch1-1

All packages are up-to-date.

Several times a day the laptop unexpectedly freezes. No keyboard/mouse/tty available. The only thing you can do - is to hold the poweroff button.

The last things in the kernel log are:

journalctl -b -1 -k

...
Dec 03 12:36:00 MSI2 kernel: i915 0000:00:02.0: [drm] *ERROR* [CRTC:131:pipe B] flip_done timed out

Any ideas?

Those two statements are not compatible. Does upgrading your kernel version to the current package help?

And do you have the CPU µcode installed and loaded?

Re: Laptop unexpectedly hangs, only hard-reset helps

Changing the kernel gives no positive effect.

However, I figured out the answer. A discussion has been posted at https://gitlab.freedesktop.org/drm/intel/-/issues/8685 on Freedesktop.
Where a large number of people complain, they all have the exact same issue with the same symptoms.

The Intel i915 video diver is the root of the problem that affects all of us. The solution is to add

i915.dmc_firmware_path=

kernel parameter at startup, which resolves the problem.
