Hi LordBob,

 

I received your e-mail to our support box on this topic and must say I'm a little at a loss for this one myself.  Hard lockups can typically be diagnosed if we see kernel panics while tailing the log via command line with a locally attached monitor and keyboard, but if there is nothing printing out to the log when the crash occurs, then there is no smoking gun for us to track.  The main things I would try to check would be:

 

1 - BIOS updates.  I know that in the past, BIOS updates to the motherboard have resolved issues regarding stability, especially when leveraging features such as virtualization.  Check to see if there is one available for your system and give it a shot.

 

2 - Try the latest RC release of 6.4.  If you can afford the risk to try an RC-release on your hardware, I would suggest doing so.  You can gain access to the release here:  

3 - Try it on another network / location.  If it is indeed something at the network layer causing a system hangup, it'd be helpful to identify that as the cause for sure by simply moving the system to a new network and see if the same result occurs.  Even just a basic switch by itself sitting between a client machine and the server would be enough.

 

 

Thanks for the reply.  I will give the RC 6.4 a try since this is just my personal server.  Unfortunately there is no way for me to try another network.

I am on the latest BIOS.

Searching for history of P8P67 Pro boards there are other cases where a lockup would bring down the network connected to it.  Here, around post #87.  Google will net other similar/same cases as well.  There are some ACPI errors in your log, but didn't find anything related to the main issue and seems to be common issue with 4.9.x kernels.

That sounds like that's the cause.  Thanks for posting that.  I literally never had this issue before I installed UnRAID.  Doesn't sound like there is a fix either, so I will have to live with it until I upgrade the motherboard.

 

At least I know what the cause is now.

 

Thanks for all the assistance.  I suppose we can mark this as solved.

Haven't followed any of the research, but why would it not work to disable the onboard network and use a pci/pcie ethernet card?

Didn't think of this to be honest.  I have no idea what the issue with the motherboard is either, so it's possible this won't make a difference.

 

I think I have a spare gigabit NIC to test.  I will try this over the RC install since I don't really think the RC version would fix this.

I swapped the network cards out last week, and have not had an issue since, although I need to wait at least another month to be sure.

 

Thanks for the help, I probably would not have found the info on the bug with the motherboard.
