The issue is still present on a 5.15 kernel. On a HP Pavilion 17-0e50sf (Hybrid Graphics: Intel_i915/AMD_radeon ), the system hangs for about 40 seconds after the user login (tested with gdm, lightdm / GNOME, Weston, xfce / Xorg, Wayland).

Blacklisting the radeon and amdgpu modules allows me to work around the problem ** Tags added: regression-release ** Tags added: kernel-bug -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1728388 Title: Infinite loop on boot when loading ACPI To manage notifications about this bug go to: https://bugs.launchpad.net/linuxmint/+bug/1728388/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
