7addfafe73e0 and c941b82e1c31 panic, edacf4b4824a does not. 

From what's pictured, I guess that these panics result from the TSLOG part of my stash at <https://reviews.freebsd.org/P601>, which I routinely apply before building world and kernel. 

Reminding myself that currently running edacf4b4824a is similarly -dirty (from application of the same stash): 

% uname -aKU

Hmm. I still get panics after installkernel with d9fee1d02178. Built without the Git stash that includes TSLOG. From my tcsh history, before build began: 

  1957  19:06   git -C /usr/src reset --hard HEAD

Maybe I'm misinterpreting what's in the photograph. 

Should I try a make clean? 

Maybe relevant: I use ccache. 

In any case: I'll take a look at some other things. 

I have vboxdrv_load="YES" in my loader.conf(5), the kernel module built in a 1400094 jail, I'll try commenting out this line …

Not a bug. A few more than the usual number of kernel modules needed to rebuilt, this number took me by surprise. 

Apologies for the noise.
