A test kernel is available here: https://kernel.ubuntu.com/~juergh/lp1946368/
I'd appreciate it if people who suffer from this problem could take it for a spin and report back. Make sure to use full kms, i.e., dtoverlay=vc4-kms-v3d and also verify that you're actually running the test kernel: $ uname -a Linux rpi-4b-rev1d4-d9f5 5.13.0-1008-raspi #9+20211014.git9545d93d SMP PREEMPT Thu Oct 14 09:46:28 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1946368 Title: HDMI output freezes under current/proposed impish kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1946368/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
