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.

this one is cool too
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 ?

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.

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 ?

memtest86+ is probably the best bet.

Ok Thanks for your help. I will try this.
