It's isolated to that particular revision, which appears to have reworked the enumeration of the available devices to boot from. Reverting only sys/boot/efi to anything before 313333 (e.g. "svn update -r 313332 ." in src/sys/boot/efi) and rebuilding results in a loader.efi that successfully loads and starts the kernel. -- Karl Denninger k...@denninger.net <mailto:k...@denninger.net> /The Market Ticker/ /[S/MIME encrypted email preferred]/
