Created attachment 246582 [details] Crashed boot loader Bootloader of 14.0-RELEASE crashes immediately (you don't get to see the boot menu) on AMD Ryzen 5 3600. This happens both with a direct 14.0 install and when upgrading from FreeBSD 13.2 (13.2-RELEASE works fine, though). See attachments for more details. Let me know if you need any additional information.
