I can boot 12.2-RELEASE AMD64 via USB just fine, but if I burn it to a DVD I cannot boot it successfully on a Thinkpad R400 or R500. I get this error: ERROR: cannot open /boot/lua/loader.lua: no such file or directory The exact same DVD works fine on a Dell T5400 desktop, however. My 12.1-RELEASE DVDs boot just fine on the Thinkpad R400 and R500. This might be related: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=238749
Also, bug 249332 on i386.
