--- Comment #1 from Andriy Gapon <avg@FreeBSD.org> ---
Just in case, the secondary traps were in wrmsr as well, but in lapic_ipi_raw
(maybe when trying to IPI other logical CPUs):

   0xffffffff80dd9932 <+114>:   mfence
   0xffffffff80dd9935 <+117>:   mov    %edi,%eax
   0xffffffff80dd9937 <+119>:   mov    $0x830,%ecx
   0xffffffff80dd993c <+124>:   wrmsr
