Created attachment 220249 [details] core file Hi! After a Freebsd upgrade the system reboot after a random time with this error: "Fatal trap 12: page fault while in kernel mode" When I return to 12.0 the system looks stable. As attachment the last core.txt.

Hi, I have just realized that I have this problem with old kernel too. Sorry for that. It's a random error, I didn't have this problem in the past and after I switched on old kernel the system had been working for a while before it crashed in the same condition. Perhaps it's a hardware problem. Is it possible that a problem with memory or SSD cause this kind of error ?

(In reply to Michaël from comment #4) Yes, this looks like some sort of hardware problem. Faulting on an address like 0xffffffb481ea9b18 is pretty strange. I would suggest trying to run a memory checker.

(In reply to Mark Johnston from comment #5) Thx. I tried memtest but I didn't succeed to identify a fault with this. I have noticed however that the memory size checked was under the real memory installed. I think that's becaus this tool run in userland, and I need to do that at boot time. Do you know a good memory checker I could use ?

(In reply to Michaël from comment #6) memtest86+ is probably the best bet.
