>Description:

I can not complete atf test runs on this machine in -current.
It works till the (long, cpu intensive) libarchive test:


lib/csu/t_ifunc_static (104/844): 1 test cases
    ifunc_static: [0.475015s] Passed.
[0.478851s]

lib/libarchive/t_libarchive (105/844): 1 test cases
    libarchive: 

and then (quite some time into the test) just reboots, no panic messages or
anything.
