ASROCK B850M: UEFI boot freeze after bootloader load

Hello,

running a small server system with most recent CURRENT on an AM5 mainboard ASROCK B850M Pro-A,
the last working firmware with FreeBSD seems to be 3.50. Upgrading to 4.03 (with some minor
optimizations for JEDEC/memory specs and preliminary support for upcominng AMD Zen5 CPUs)
leaves the system with the initial loader message dumping some informations about the used
screen resolutions in a frozen state. Not keyboard (USB), nothing, the box is dead.
I also tried the latest flash image provided by snapshot service,
FreeBSD-16.0-CURRENT-amd64-20260126-8ef8c6abfadf-283376-memstick.img. Same result. The same
with the official 15.0-RELEASE USB flashdrive or 15-STABLE snapshot.

I tried an older Ubuntu (EFi boot), which worked. Maybe this is a minor issue.

Kind regards,
oh
