[Kernel] Black Screen / Fail to Boot with Intel Iris Xe (11th Gen) on Kernel 6.17.4

[imvitorxz]

Hi,

I am reporting a regression that causes a black screen during boot after updating the kernel on an 11th Gen Intel Iris Xe system. The working kernel is 6.16.3, but the latest kernel (6.17.4) fails to load the OS.

1. Environment & Hardware Specs
   OS: Pop!_OS 22.04 LTS (Jammy)
   Model: Acer Aspire A514-54
   CPU: 11th Gen Intel® Core™ i5-1135G7
   GPU: Mesa Intel® Iris(R) Xe Graphics (TGL GT2)

2. Kernel Status
   Functional Kernel (currently running): 6.16.3-76061603-generic
   Broken Kernel (newest version): 6.17.4-76061704-generic

3. Steps to Reproduce

4. Update system, which installs kernel 6.17.4.

5. Select the current kernel (6.17.4) entry from the Systemd-boot menu.

6. Actual Behavior
   The system does not initialize the GUI or reach the login screen; it results in an unrecoverable black screen.
   Attempting to boot with the nomodeset parameter also failed to load the system.

7. Temporary Fix Applied
   To maintain stability, I have reverted to and blocked updates for the functional kernel (6.16.3) using sudo apt-mark hold linux-generic linux-headers-generic. I also removed the broken boot entry (pop_os-current.conf).

Confirming I encountered the same issue on a Dell XPS 15 9520 (Intel 12th Gen Core i7-12700H) with Intel Integrated Graphics, running Pop!_OS 22.04

Using the 'oldkern' systemd-boot entry made the problem disappear.

As a side note, no such issues have been encountered on my Pop!_OS machines running 24.04 (beta) with AMD Processors (a Thelio desktop & a Framework 13), and issues have been reported here by other 24.04 beta users running on Intel processors.

Therefore it seems this issue is specific the combination of this Kernel version and Intel Chipsets, and not a specific Pop!_OS release. I've also seen some vaguely similar reports about boot issues with 6.17.x kernels on mainline Ubuntu distributions

If this is the same as #398, then it's likely going to be fixed by #397 (22.04) and #396 (24.04).

@jacobgkau I see you mentioned on those PRs that they resolve errors related to timing out waiting for udev. I can confirm that I did see errors related to timing out waiting for udev. So I think you're right. I'll keep an eye out for kernel 6.17.9
