pciehp device already exists cannot hot add device

I get above error upon boot white on black before Plymouth. It has appeared on last three kernels & only middle (kernel sandwich) & I assume earlier, will boot.

:\

Hi
If you add the boot option;


pciehp_force=0

Then after the system is up run;


 modprobe apciphp

Does this help?

Added as kernel parameter, but still hangs first splash (Plymouth?)

Disable plymouth (“plymouth.enable=0”) to see where it hangs exactly, I’d say.
