Futro s920 + DELL INTEL PRO X3959 crash on heavy load

Hi,
Just to make sure I added some thermal paste to the cpu and temps did go down but the crash is still ocurring, so I don't think the problem is because of high temperatures.I am runing an iperf server on the machine and sending traffic from a local computer of the net (so it hits lan interface, em0).
Thanks,

guide me on how to enable serial output?
See https://docs.netgate.com/pfsense/en/latest/hardware/console-types.html
The functionality and how to set it up will depend on details of what your hardware actually provides.
Netgate does provide more specific details on the hardware they sell. -

Hi Patch,
Thanks! I read the docs but I currently do not have a serial cable around :S
But isn't the output of serial console the same as sshing/reading DisplayPort output? When i ran this tests and were reading the screen output of the pfsense, nothing important was shown. It just went off and rebooted.
Please correct me If I am saying something crazy.Thanks,
Manuel -
It's same as a video console but you can't log that unlike a serial output. So if it spews a wall of text at you or reboots when you're not looking you won't be able to analyse it.
If nothing at all was shown, it just hard resets immediately, that's almost certainly a hardware issue.

Hi Steve,
Yeah, nothing happens. It just reboots :sThe curious thing is that running iperf on Linuxstress does not trigger this hard reset.
Also, if the test is run just after a startup (cold system) sometimes the test does not fail. But it always does once the temps are high. Is the system maybe rebooting due to temperatures?
Is there anyway to check that with pfsense?Thanks,
Manuel -
Sure you can check the CPU temp. It will show on the dashboard if you enable the senor in Sys > Adv > Misc.
However it may be some other component overheating.
How are you testing with Linuxstress?

@stephenw10
I have seen that the crash is at +/- 80C° and 100% CPU usage.
I am testing with a live USB of Linux Stress.Thanks,
Manuel -
The CPU core is running at 80°C?
That seems hot, what CPU is it?How hot does it run at idle?
Is the system fan spinning up with temperature as expected?

@stephenw10
It runs at 60/70 normally. It does not have a fan. It is a passively cooled CPU.Thanks,
Manuel -
Hmm, well that's not so bad then. Anything passively cooled it expected to run hot. But that is still very hot. What is the actual CPU in that?
-
Ah, Ok I see it's an AMD GX-415GA?
Hmm, that appears to have a max rated temp of 90°C. In which case 80 seems waay too close!
It looks like it has a pretty big heatsink and the case is full of holes so the first thing I would do it just point a desk fan at it. It should make a pretty huge difference to the temps.

Hi Steve, thanks for keeping up!
I have made some tests with low temps (60Cº) and it took more to fail but it did fail anyway. I don't think this one was due to the temps but who knows... I am really out of options rn.
Anything else I can test/investigate?Thanks,
Manuel -
@manu_hna @stephenw10
I tried the desk fan approach but no luck... The pfsense application still crashed.Thanks,
Manuel -
You set the sensor to amdtemp? Those are actually the reported CPU core values?
How old is that device? It looks like it could be almost 10 years in which case it could just be failing components if it's seen a lot of hours.

Hi Steve,
Yes those are amd sensor. Maybe this unit has gone bad. Just as a test I tried same iperf with opnsense and openwrt and same results occurred...
I have ordered a new one and I'll see how this goes.Thanks, Manuel

Hi!
Just to close this. Bought another unit and it is now working perfectly. So it was, indeed, faulty hardware.
Thanks @stephenw10 and @Patch for the help.Manuel
