+++ This bug was initially created as a clone of Bug #1222082 +++

SD-Ticket:  https://sd.suse.com/servicedesk/customer/portal/1/SD-149531

After troubleshooting the SD-Ticket I was referred to open this BSC

Upgrade of openSUSE 15.4 to 15.5 on my Lenovo P16 notebook went well. After the upgrade the Thunderbolt docking station is only recognized “half”, means network (wired) and 2nd monitor isn’t working anymore.

Known firmware issue with openSUSE? BIOS and Thunderbolt Dock 4 (TBD4) firmware meanwhile updated to latest.

Comment 1 Takashi Iwai 2024-04-02 12:42:55 UTC

At first, verify whether the issue is seen with the latest upstream 6.8.x and 6.9-rc kernels from OBS Kernel:stable:Backport and Kernel:HEAD:Backport repos.

Then, please boot with boot options "drm.debug=0x1e log_buf_len=16M", and upload the dmesg outputs from both working and non-working kernels.

Comment 2 ralph roth 2024-04-02 13:14:32 UTC

6.8.2 - didn't work details see BSC#122082, also there is the dmesg.txt file provided

Thanks.  Also please give the log with debug option from the good working case (SLE15-SP4 kernel), too.

As I have cold installed 15.5 the 15.4 kernel will not work anymore with the dock (2nd monitor didn't work. Network depends on the BIOS workaround)

Comment 8 ralph roth 2024-04-02 14:51:13 UTC

I have an old Dell Inc. Precision 5520/080VVT with Leap 15.5

with this setup the TBT4 dock works (NIC+2nd monitor)...

Comment 9 ralph roth 2024-04-15 08:01:45 UTC

Tried all available Kernels so far.
Any idea how to proceed?
