Hello,
I experienced numerous freezes during the boot of OpenSuse Leap 15.6 (kernel 6.4 or 6.14) and noticed that they occurred when loading the i915 video driver.
Many people talk about PSR and disable it by adding the following command: i915.enable_psr=0
On my Meteor Lake, this produces the opposite effect: almost systematic freezes, so I added i915.enable_psr=2 and since the phenomenon has disappeared 99% of the time.
I hope this helps others
Did you try using the Xe kernel driver with the 6.14 kernel instead of i915? i915 dates back originally to new in 2004 technology for chipsets supporting 32bit Pentium 4s. September 2020 brought a new Intel graphics technology called Xe, for which a new driver technology was introduced. Introduction of Meteor Lake (with Xe) followed over 3 years later in December 2023.
Xe Driver:
not yet completed:
https://www.kernel.org/doc/html//next/gpu/rfc/xe.html
needs new kernel:
The i915 kernel driver will continue to be supported for all existing hardware.
I see no date at that URL. I should think the newest kernels and newer GPUs to be farthest along in development, for which 6.14 and Meteor Lake should qualify. Once OP determines his own device ID, he could try the i915.force_probe=!#### xe.force_probe=#### method to test. Xe works in my 3 year old Rocket Lake, though when last I tested, not remotely as well as i915 worked.
I’ve tested the xe video driver , it boot fine but when i open a youtube video in full screen mode the video does not play smooth
May need codecs.
You may run test glmark2 from OSS repo to check the relative performance of the two drivers. My Rocket Lake using Xe turned in only 740 when I last checked, compared to 2900 with i915. If you have similar comparability you may need to continue using i915 too, unless there’s other backport software you need, or codecs.
It may be worth booting a live TW or 16.0alpha media as a check. Indeed if you try 16.0 and get same result, a bug report is probably the best next step.
I’ve installed all the pacman codecs, same issue with XE
glmark2 with i915 = 1888 , CPU temp 70°c
glmark2 with XE produced errors (failed to set swap interval) and CPU temp 90°c
I will keep the i915 video driver and the i915.enable_psr=2 until stable XE version
So far the Kubuntu liveCD with the i915 video driver has never frozen on boot
Thanks you all
I checked the PSR mode in the last Kubuntu live CD
sudo cat /sys/kernel/debug/dri/0000:00:02.0/i915_edp_psr_status
PSR mode: PSR2 enabled
By default in LEAP 15.6 (Kernel 6.4 or 6.14) the same command return
PSR mode: PSR1 enabled
Also try to use newer Mesa 3D from X11:XOrg repo:
