I also get this problem with a -CURRENT built today. I also updated the =
files on the MS-DOS boot partition to those of the most recent =
11.0-CURRENT snapshot =
(FreeBSD-11.0-CURRENT-arm-armv6-BEAGLEBONE-20141222-r276066.img.bz2), =
but I get the same panic.
Here is the boot output typescript:

The BEAGLEBONE-NO_WITNESS kernel config file is the BEAGLEBONE config =
