Intel 82576 (Pro/1000VT) crashing system

[Ben.]

Hi,

I am running a Fujitsu S930 Futro Thin Client with a Intel Pro/1000VT (Dell P/N 0H092P) attached to the PCIe x4 Port.
It's quadport card which is identified as a Intel 82576 card.

The 4 ports are configured as a LAGG interface.

Once I put some load on one of the ports, the system reboots. In the logs there is nothing. I could not even catch something that would be shown on the screen.

Has anybody faced a similar issue and has a hint what I could do?

In the tunables I set

Code: [Select]

hw.pci.enable_aspm = 0but it didnt change anything.

Thanks for hints what could solve my problem.

OPNsense 21.7 or 22.1?

[Ben.]

22.1, but I never used 21.x on this machine. I just bought it.

[heyheyheyhey]

Have you tried updating the nic firmware?

[Ben.]

No, I didnt. I tried to find out how it works and where to get the firmware, but I didnt succeed.

I assume the card has a hardware/AMD compatibility issue as it also causes reboots under Linux.
I read in another blog that AMD embedded CPUs und those Intel NICs can have issues working together. At least that guy also faced reboot issues.

The BIOS of the S930 is current though.

i use the same setup with the exact same issues... did you find a way to fix it?

[Ben.]

Sadly no. I just found several people reporting about the same issue.

I replaced the NIC with a Broadcom card which is working fine.

[kevo!]

sh!t...that wasnt the answer i hoped to hear those Broadcom nics are quiete hard to get... i made a test installation with pfsense... same behavior...

thanks for the qick reply

[kevo!]

hey ben.,

which broadcom card did you use? i bought a BCM5719 now the s930 wont boot....

any idea?

kevo

[Ben.]

Exactly your model from Dell.

Dell Broadcom 5719

So far no issues but no heavy testing yet. But boots and didnt reboot/hang after iperf tests.
