The system is the next system:
MSI B450M-PRO M2 MAX
PS/2 and mouse Keyboard
AMD Ryzen 5 3400G
16 GB DDR4 3000 MHz XMP (Corsair)
hrev56350.
attached KDL Screen photo taken with my mobile, while booting from a 4 GB SD Card.
have similar issues with b550 chipset
Behaves differently on my ga-z97-hd3 with Intel i7 4790, It hangs completly.
Please try enabling “Fail-safe video mode” in the BIOS.

Sounds odd, but try setting that boot device to the highest priority in the BIOS (i.e. Don’t use the boot menu and don’t override from the BIOS). Magically fixes booting on my B450.
Yeah but another problem is that behaves differently on different mainboards. With 7 different computers in my house and in ones booting in UEFI Mode works well(as well as legacy) in others legacy does not work or UEFI does not work(simply hangs or other things. When the normal thing is to boot correctly on UEFI and on Legacy even with modern computers. Some strange things happening

Yeah, it’s definitely not stable - but did you try my suggestion? I could get it to boot when selecting from the boot menu with various safe options and the like, but simply putting it to the top in the BIOS made it boot every time (with safe mode graphics)
Had the same problem with my Lenovo ThinkPad T495.
The answer is in the BIOS :
In Security Tab :
- disable secure boot
In Startup Tab :
- UEFI mode,
- disable CSM support
In Restart Tab :
- disable OS Optimized defaults
Without those points, it can not boot and I have this same white screen with failures.

In my case is a Vega 11 IGP which i think is not supported, but in never releases should boot at framebuffer driver which is kindly odd.
