I'm seeing the same thing with 20.04 when running any of the 5.13 kernels. Last tested with 5.13.0-41.
My setup is an ASUS Hero XIII motherboard. Monitor plugged in, with a second monitor plugged in via a USB / HDMI adapter (not sure if that is relevant) I had to remove iwlwifi-ty-a0-gf-a0.pnvm and iwlwifi- ty-a0-gf-a0-63.ucode to get wifi to work, but the boot hangs with any 5.13 kernels. Only 5.11 will work, unfortunately.

I'll see if there's anything else to try - maybe around that ibt-0041-0041.sfi firmware -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947618 Title: [i915] CPU locks up on Ubuntu 21.10 boot when 2 displays are connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1947618/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
