[..] Bruce Simpson has asked the same thing. I'll just attach my answer to him to this mail. It does not, however, include the system tunables, and I cannot include a sysctl -a output right now (the machine just crashed again, this time again inside of WITNESS, a separate email will document this). But IIRC I have removed all tunables from /etc/sysctl.conf and /boot/loader.conf As I told Bruce, I have never set debug.mpsafenet (in case you are especially interested in this tunable).

I use the em(4) driver. I did not change the debug.mpsafenet setting (awaiting Robert's OK, that the changes are now merged completely). If you need more information about the machine and kernel, please take a look at PR kern/68442.
