[Bug 1860284] Re: thinkpad thunderbolt 3 dock gen2 with pci memory allocation errors on Yoga C940 unless plugged in before boot
I'm also affected by this bug on 20.04 with the HWE 5.13 kernel (currently: 5.13.0-30-generic #33~20.04.1-Ubuntu SMP Mon Feb 7 14:25:10 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux). My PCIe Thunderbolt card (ASUS ThunderboltEX 4, Intel JHL8540 controller) only partially works: the USB part works and USB devices plugged into the dock are recognised and functional (including the dock's built-in Ethernet interface), however there is no video signal coming from the dock's DisplayPort ports. I've tried the patch mentioned in the kernel bug tracker [1], but it doesn't fix the issue.

Hi, sorry about this. I did not get any comments from x86 maintainers for this and the comment from Bjorn (the author of the original code) seems to suggest rather big rework so I simply haven't had time to look at it at the moment.
