I can't reproduce this on my BBB. I sync'd to the exact rev you used and rebuilt, installed it all on an sdcard and booted, and I boot all the way to the login prompt. I even diff'd my boot messages against the ones you posted and there are no significant differences other than pathnames and compile times. Maybe a stack backtrace would help... enter 'bt' at that db> prompt and post the output (everything from the vm_fault(...)-> 1 to the end of the backtrace). -- Ian
