Hi! Just updated to r331345. Two problems: 1. boot/efi.4th is added to /usr/src/ObsoleteFiles.inc but still included in loader.rc. Loader fails to load it and subsequently fails to load modules. Reinstalling efi.4th problem 2 appears. 2. Fixing problem 1 and adding efirt_load="YES" to /boot/loader.conf makes the kernel panic instantly.
