I had ssh interactive session all the times it paniced. There were no panics with such configuration in 6.2-STABLE which kernel had IPSEC compiled in, so debug.mpsafenet was forced to 0. But recently I've upgraded to RELENG_7 that has MPSAFE IPSEC implementation and has no debug.mpsafenet tunnable so I can't make it off to test.
