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. Some of the bluetooth startup info when it fails (5.13): Bluetooth: Core ver 2.22 NET: Registered protocol family 31 Bluetooth: HCI device and connection manager initialized Bluetooth: HCI socket layer initialized Bluetooth: L2CAP socket layer initialized Bluetooth: SCO socket layer initialized Intel(R) Wireless WiFi driver for Linux iwlwifi 0000:04:00.0: enabling device (0000 -> 0002) iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-63.ucode failed with error -2 iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-62.ucode failed with error -2 iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-61.ucode failed with error -2 iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-60.ucode failed with error -2 usbcore: registered new interface driver btusb iwlwifi 0000:04:00.0: api flags index 2 larger than supported by driver iwlwifi 0000:04:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 93.8.63.28 iwlwifi 0000:04:00.0: loaded firmware version 59.601f3a66.0 ty-a0-gf-a0-59.ucode op_mode iwlmvm Bluetooth: hci0: Firmware timestamp 2022.9 buildtype 1 build 40196 Bluetooth: hci0: Found device firmware: intel/ibt-0041-0041.sfi Bluetooth: hci0: Boot Address: 0x100800 Bluetooth: hci0: Firmware Version: 175-42.20 The startup info when it succeeds (5.11): Bluetooth: Core ver 2.22 NET: Registered protocol family 31 Bluetooth: HCI device and connection manager initialized Bluetooth: HCI socket layer initialized Bluetooth: L2CAP socket layer initialized Bluetooth: SCO socket layer initialized usbcore: registered new interface driver btusb Reached target Bluetooth.

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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1947618 Title: [i915] CPU locks up on Ubuntu 21.10 boot when 2 displays are connected Status in linux package in Ubuntu: Confirmed Bug description: I've updated from 21.04 to 21.10 and that bug has appeared in kernel 5.13.0-19. When 2 displays are connected simulateneously (DP and HDMI) before graphics server is started the kernel hangs up and reports that cpu is locked up. Boot with 5.11 kernel doesn't produce that problem. PC is based on i7-11700 CPU.
