This bug is awaiting verification that the linux-azure- fips/6.8.0-1034.39+fips1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-azure-fips' to 'verification-done-noble-linux-azure-fips'. If the problem still exists, change the tag 'verification-needed-noble-linux-azure-fips' to 'verification-failed-noble-linux-azure-fips'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

This bug is awaiting verification that the linux-oem-6.8/6.8.0-1007.7 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.8' to 'verification-done- noble-linux-oem-6.8'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.8' to 'verification-failed-noble- linux-oem-6.8'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

** Description changed: SRU verification for oem-6.8-noble: [Impact] In https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.5/+bug/2046315, we've cherry-picked the 8 patches from the most recent mainline kernel to oem-6.8 to fix the panel flickering problem in the Dell OEM project. However, - OEM reports that the patches don't solve the problem in some machines. + OEM reports that the patches have regression on 6.8.0-1006-oem. For now, we apply the workaround patches from oem-6.5 to fix the bug. In the meantime, we've reported the issue to Intel and are waiting for the fix. Once the fix is available in the mainline kernel, we'll backport the fix into oem-6.8 kernel and revert the workaround patches. Upstream bug: https://gitlab.freedesktop.org/drm/intel/-/issues/9739 [Fix] Apply workaround patches from oem-6.5 to oem-6.8 [Test Plan] The machines mentioned in the attachment (containing the problematic panel's EDID) would have flickering graphics with the linux-6.8.0-1006-oem kernel. The flickering graphic is gone after applying the workaround patches. [Where problems could occur] - The workaround patches add some quirks that disable PSR2 on some panels. So far, there are 7 panels listed in the quirks (other panels used by OEM products are flickering-free without the patches). + The workaround patches add some quirks that disable PSR2 on some panels. So far, there are 7 panels listed in the quirks (other panels used by OEM products are flickering-free without the patches). If OEM starts using other panels in the future, it's not sure that the panels will be flickering-free. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069993 Title: Panels show garbage or flickering when i915.psr2 enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.8/+bug/2069993/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
