Understood. I hope you'll have a great time debugging/testing :) Could you please try adding the `pcie_aspm=off` boot-time parameter to disable PCIe ASPM?
You can follow the instructions below: 1. Open /etc/default/grub via any text editor 2. Find the line `GRUB_CMDLINE_LINUX_DEFAULT=...`, then append `pcie_aspm=off` at the end of the string: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off" 3. Update the grub configuration by: $ sudo update-grub 4. Reboot the machine, and see if the problem is gone Note: disabling ASPM might make some devices unable to work, and it's not good for power saving. So this is just a temporary workaround/debug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2115880 Title: AMDGPU: Main laptop screen flashes regularly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.14/+bug/2115880/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
