      Hi PfSense Experts,

      We are facing very odd issue with pfsense, It crashes frequently one or twice a day gets mount root error on boot therefore we have to forcefully powerdown system , once we reboot it is report like  pfSense has detected a crash report or programming bug. We have attached crash report here.  Is this could be hardware issue?

      I would highly appreciate if someone please help us in this matter.

      Thanks & Kind Regards,
      Nirav

        Your hardware is broken.

        MCA: Bank 4, Status 0xb200000000070f0f
        MCA: Global Cap 0x0000000000000105, Status 0x0000000000000004
        MCA: Vendor "AuthenticAMD", ID 0x20ff2, APIC ID 0
        MCA: CPU 0 UNCOR PCC BUSLG ??? ERR Other timed out
        panic: Unrecoverable machine check exception
        cpuid = 0
        KDB: enter: panic
        
        

        MCA/MCE errors can only come from hardware. There is no way for a software issue to trigger them.

            Hardware event. This is not a software error.
            CPU 0 4 northbridge 
              Northbridge Watchdog error
                   bit57 = processor context corrupt
                   bit61 = error uncorrected
              bus error 'generic participation, request timed out
                         generic error mem transaction
                         generic access, level generic'
            STATUS b200000000070f0f MCGSTATUS 4
            MCGCAP 105 APICID 0 SOCKETID 0 
            CPUID Vendor AMD Family 15 Model 47
            
            

            Nothing there sounds good, it also doesn't point to any one specific thing.

            Given that seems to be a >10yr old CPU, it's probably time to consider a replacement box.

            AMD	0F	2F	K8 (rev.E)	   Athlon 64  Sempron
