The panic you got is a "should never happen" panic. Note that in the code line sourced, the second argument to mtx_assert() is MA_OWNED. The panic is saying that it is some invalid value (i.e. something other than MA_OWNED). Given that is a constant, that's not very likely at all barring some hardware glitch. You do have a somewhat scary looking machine check logged before your panic: MCA: Bank 1, Status 0xd000000000000171 MCA: Global Cap 0x0000000000000105, Status 0x0000000000000000 MCA: Vendor "AuthenticAMD", ID 0x20fc2, APIC ID 0 MCA: CPU 0 COR OVER ICACHE L1 EVICT error It is a correctable error, but given the nature of the panic I'd suspect a hardware problem. mcelog doesn't provide many more details: HARDWARE ERROR. This is *NOT* a software problem!
