Device: Lenovo Thinkpad T16 Gen 2 AMD

Current Kernel: Linux 6.5.0-1024-oem

Expected:
Connect external display Samsung LC34J791WTU LED (34") over thunderbolt and get video signal.
--
What happend instead:
External display is detected but no video. Blackscreen instead. I need to manually choose older kernel "Linux 6.5.0-1023-oem" during boot to get video signal correctly. Seems like something broke in 6.5.0-oem-1024 release
Additional info:
Same wrong behaviour on linux kernel 6.5.0-41-generic but video works on older 6.5.0.35-generic selected during boot.
