Re: FreeBSD wont boot on AMD Ryzen 9 7950X

Hello,

Thanks for the info. At least I know it's not specific to my parts. Is
there any knob one can turn in the BIOS to enable/disable this feature?
iirc UART is old school serial ports? Wonder if removing UART support from
the kernel would be a workaround.

Thanks.
