this one is cool too
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. (In reply to Mark Johnston from comment #7) Ok Thanks for your help. I will try this. Please re-open if you're still seeing crashes on newer versions of FreeBSD. |
