Reporter, Can you verify if you have same issue on latest drm-tip: (https://cgit.freedesktop.org/drm-tip) with kernel parameters drm.debug=0x1e log_buf_len=4M. If the problem persists attach the full dmesg from boot. Reporter, any updates here? Lakshmi, thank you for the reply i will report back as soon as i have tested latest drm-tip this system is used for multiple server applications so reboots do not happen often, please bear with me Hi. This issue really looks like these: https://bugs.freedesktop.org/show_bug.cgi?id=107951 https://bugs.freedesktop.org/show_bug.cgi?id=106478 Could you please check the same with Vadym on your system? (more info on the first link, pasting only the "final" investigations below): Following patch fixes the issue for me: https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/877396/ That patch fixes similar issue on the ChromeOS.

Vadym, thanks, i have applied the patch but the problem is the same for sanity i have attached the `intel_display.c` i used for this build (`git apply` and also `patch` command failed for me, so i added the patch line manually) Yep, it doesn't work for me as well. There is a link to original fix (in ChromeOS) in that patch, so that is why I thought it should fix the problem. I can confirm that for me only original patch https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/877396/3/drivers/gpu/drm/i915/intel_display.c works well. Reporter, can you try with the original patch as mentioned in comment#10? Will that help? Created attachment 142416 [details] [review] drm-tip.head.852b9329fbb6ea8bdbb3dac78328aae73d919305.patch (In reply to Lakshmi from comment #11) > Reporter, can you try with the original patch as mentioned in comment#10? > Will that help? Lakshmi, i can confirm the patch works, but more code is in the new drm-tip head which requires butchering compared to the old patch, i have attached my patch (built from latest drm-tip, head 852b9329fbb6ea8bdbb3dac78328aae73d919305) the latest head still has the glitch when not patched. i am happy to help if you want me to test any further patches, please let me know. thanks for the help Ville, any help here?
