Hmmm, actually, I think that the kernel on the ISO was compiled with
KTR, so you just need to set the mask (no recompile required), using
either a loader tunable ("set debug.ktr.mask=0x2000000" on the loader
prompt) or sysctl ("sysctl debug.ktr.mask=0x2000000"). Since it
doesn't seem to happen during boot the sysctl method should suffice.
