[SOLVED] Kernel 6.8.8 breaks Dell docking station

When upgrading from kernel 6.8.7 to 6.8.9 my keyboard (Kinesis Advantage 2) connected to (Dell) monitor's USB-hub, which in turn is connected to a Dell TB16 docking station, and my wired Internet (through same Dell TB16 docking station) stopped working.

(EDIT: I've tried 6.8.8 and it has the same issue as 6.8.9)

"stopped working" = I can not use the keyboard connected through USB to type in password for encrypted disk during boot sequence, nor does it work afterwards. I get an error message (se code snippet below).

Downgrading back to kernel 6.8.7 solves the issue.

Long term, I'm curious to hear what would be the way to solve this?

Perhaps plug the Dell docking station into a windows PC, and upgrade its firmware?

The Error message during boot-sequence (note: ran tesseract OCR on picture of screen displaying the error, so might be some characters off below / typos):

Please enter passphrase for disk home (data) on /data: (press TAB for no echo) ([ 6.5212671 pcieport 0000:06:04.0: Unable to change power state from D3hot to

which then ends with:

I would suggest you try 6.8.8 from the ALA to see which version introduced the issue and 6.9.0 from testing to see if the issue has already been fixed.

Re: [SOLVED] Kernel 6.8.8 breaks Dell docking station

OK, I've tried 6.8.8, and it has the same issue, thus this is the kernel that introduced the issue.
Next up: I'll give 6.9.0 a try

Re: [SOLVED] Kernel 6.8.8 breaks Dell docking station

I think I run into the same issue with my Caldigit TS3 Plus Thunderbolt 3 dock:

https://bbs.archlinux.org/viewtopic.php?id=295518

Loqs was very kind and suggested to try specific kernels and bisection, but I've not yet been able to investigate because this happens on my office PC.

I also opened an issue on Archlinux Gitlab:

https://gitlab.archlinux.org/archlinux/ … /issues/48

The issue persists with the latest kernel, 6.9.1. The latest working kernel is 6.8.7.

Re: [SOLVED] Kernel 6.8.8 breaks Dell docking station

Good news! The kernel parameter thunderbolt.host_reset=false should fix the issue.

Re: [SOLVED] Kernel 6.8.8 breaks Dell docking station

I'll have to try that, thanks!

(Although, sadly, that will be yet another tweak, to make hardware work.)
