Hi Thorsten,
I'll try to provide a kernel log ASAP, it's not that easy because when I run into this issue my keyboard isn't working. The kernel parameter that Mario suggested, thunderbolt.host_reset=false, fixes the issue!
I can add that without the suggested kernel parameter the issue persists with the latest Archlinux kernel 6.9.1.
I also found another report of the issue on Archlinux forum: https://bbs.archlinux.org/viewtopic.php?id=295824

Hello, from 6.8.7=>6.8.8 I run into a similar problem with my Caldigit TS3 Plus Thunderbolt 3 dock.
After the update I see this message on boot "xHCI host controller not responding, assume dead" and the dock is not working anymore. Kernel 6.8.7 works great.
Thx for the report. Could you make the kernel log (journalctl -k/dmesg) accessible somewhere?
And have you looked into the other stuff that Mario suggested in the other thread? See the following mail and the reply to it for details:

Ciao, Thorsten
P.S.: To be sure the issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression tracking bot:
