      Hi,
      I'm experiencing random reboot with pfsense. I assume it is a hardware issue.
      Are there any tools inside pfsense to debug hardware issues?
      Like memory check and ssd checks?
      Thanks,
      EVS

        You can check the SMART status of the drive. You would want to boot fro something else to run a memory test.

        Do you get a crash report or any log entries when this happens?

          I got a crash report but no kernel panic.
          The crash report is very long and did find any clue what the problem can be.

            The backtrace and panic string near the top of the report should provide a clue.

                Could be any number of things. You want the values from "show cpu" to "ps" from ddb like:

                db:0:kdb.enter.default>  show pcpu
                cpuid        = 1
                dynamic pcpu = 0xfffffe0097d79200
                curthread    = 0xfffff801c2eb4500: pid 40463 "sh"
                curpcb       = 0xfffffe0064dc1cc0
                fpcurthread  = 0xfffff801c2eb4500: pid 40463 "sh"
                idlethread   = 0xfffff80003398a00: tid 100004 "idle: cpu1"
                curpmap      = 0xfffff80161811138
                tssp         = 0xffffffff82a1eb78
                commontssp   = 0xffffffff82a1eb78
                rsp0         = 0xfffffe0064dc1cc0
                gs32p        = 0xffffffff82a253d0
                ldt          = 0xffffffff82a25410
                tss          = 0xffffffff82a25400
                db:0:kdb.enter.default>  bt
                Tracing pid 40463 tid 100426 td 0xfffff801c2eb4500

                db:0:kdb.enter.default>  ps
                

                And the panic output from the message buffer like:

                Fatal trap 12: page fault while in kernel mode
                cpuid = 1; apic id = 02
                fault virtual address	= 0x30
                fault code		= supervisor read data, page not present
                instruction pointer	= 0x20:0xffffffff80cb9bdc
                stack pointer	        = 0x28:0xfffffe0064dc1450
                frame pointer	        = 0x28:0xfffffe0064dc1480
                code segment		= base 0x0, limit 0xfffff, type 0x1b
                			= DPL 0, pres 1, long 1, def32 0, gran 1
                processor eflags	= resume, IOPL = 0
                current process		= 40463 (sh)
                

                Those are just examples.

                Steve
