Hi Team,

 

I've encountered a rather odd issue and was hoping someone might have some insight. The problem is that since I upgraded to Unraid 7.0 or 7.0.1 I've had random NIC crashes. I had run the previous Unraid 6.x branch for almost a year without a crash, so this is new to this U7 version. At first I thought the server had locked up since I couldn't ping or browse but after going through the syslog to determine the cause I found this entry:

Apr 20 21:40:11 Tower kernel: ixgbe 0000:07:00.0: Adapter removed
Apr 20 21:40:11 Tower kernel: ixgbe 0000:07:00.0: Warning firmware error detected FWSM: 0xFFFFFFFF

 

Now I'm no noob when it comes to handling PC hardware so I figured let me just update the firmware on this x520 card if that really is the issue but I found this one the official Intel KB:

https://www.intel.com/content/www/us/en/support/articles/000027683/ethernet-products/500-series-network-adapters-up-to-10gbe.html

 

Basically this x520 card does not support firmware updates

 

The question I have or questions I guess are:

1. Are there any known issues with the Linux drivers for intel cards that causes this NIC crashing behavior? If so are future Unraid updates likely to resolve this problem for me?

2. If the newer drivers will keep doing this and I want to stay on Unraid 7.x going forward, what are my alternatives? Can you recommend an Intel NIC that support SFP+ for 10gb Twinax connections so I can connect to my network with full speed? It looks like most recommend the x520 or x540/x550 cards but the later only support copper not SFP. I'm guessing I will have to look at the 700 or even 800 series to find SFP+ cards but I wanted to see what you guys would recommend so I don't end up with the same issue again in the near future.

 

Thanks in advance!

I would recommend updating to 7.1.0-rc.1 and retesting, the newer kernel/driver may help.
