Mmmh, so I need to test an ubuntu kernel (6.5.0-14) because of sound issues in mainline TOT, and I can't boot the kernel to completion without hititng this hang bug. I'm not exactly sure which part of the boot triggers it. I can't patch that kernel easily. How exactly do I disable runtime PM from the kernel command line for "that device" which I'm not even sure which one it is. If it's the eth device, I already removed the igc module to prevent it from loading, and I also removed the ethtool binary, but I'm still getting the hang. On the plus side, with 6.6.8 and the old patch which I understand is not the ideal solution, I can confirm that I've been running problem free until now, so thanks again for that interim patch.
