HP Z6 G5A + NVIDIA RTX 5090 + Linux black screen, vol2

[truebest]

A couple month passed away since i post a message "HP Z6 G5A + NVIDIA RTX 5090 + Linux black screen".
Now i'm looking for help someone from HP. Recently my workstation got BIOS updates 01.01.24 - 01.01.26. After upgrade my BIOS to this in 100% cases i'll get black screen at any Linux during loading kernel. Rolling back to 01.01.23 and jiggling with Re-sizable Bar feature gives me a way to run Ubuntu.

Thanks for your support.

Actually, i double checked. It still seems fluctuated, but 
The Resizing BAR feature make scene. Disabling it gives any Linux get video out. When it enabled, Linux boot-up, and you can control your instance via ssh etc, but there is no any extra output on the screen after "Loading initial ramdisk..."
