Fedora 43 Kernel 6.17 issue with lenovo dock

Follow up topic of Fedora 37 kernel 6.1 issue with lenovo dock. I moved it to a new topic @ilikelinux

Does your Lenovo Thunderbolt 4 Workstation Dock still work?

I just got a P14s with that dock, and it makes my machine lock up on F43.

Kernel issue?: Fresh install of Fedora 43 hard locks when Thunderbolt 4 Dock is (dis)connected during sleep

Installing kernel 6.17.1-300.fc43.x86_64, while the device has stopped hard locking, it now will fail to sleep after toggeling the dock a couple times, but over-all the behaviour seems better, so yeah this does look like a kernel bug.

Yes, it works very well (including disconnect/connect behavior) with f43 on my ThinkPad X1 Carbon Gen 11. I am currently on kernel 6.17.11-300.

and you’re not getting issues with waking from sleep, or your computer locking up when trying to go to sleep?

[bfinger (Bernd Finger)]

I do not use sleep/wake up very often. If I remember correctly, last time I tried (some weeks ago) the laptop (while attached to the dock) woke up correctly and I could continue my work. I use lock/unlock screen very often and this works nicely, both connected and disconnected to the dock - even when locking the screen while connected to the dock and unlocking while disconnected and vice versa.

For me, if the dock gets plugged in or unplugged while the computer is asleep, it will make the kernel lock up entirely. No entries in the log whatsoever.
