Upgraded to 2.7.13 -- W T F --

I think we can rule out memory error


Gone 2 passes no errors.

Tried once again with no isolcpus = hangs almost immediately so isolcpus=2,3 is a must for this NUC to work in 64bit.
Will have to run more tests but I am not so happy about this NUC as it behaves like this with Debian.

Maybe the work ozzyrob puts down with a new Mint 18.3 + LCNC compilation will get thing to work, maybe?

I GIVE UP

This NUC is so unreliable as it hangs all the time!

Before you completely give up, try adding this to your kernel boot command line:

intel_idle.max_cstate=1

I didn't read back enough to see what processor your NUC has, but if it is Baytrail (and maybe some others) this will probably fix it.

This is just a brief overview.
Ok I have compiled and installed a kernel, I went with 4.11.12 as it was the closest to the Mint kernel with a RT patch.
Runs OK.

Compiled and installed Linuxcnc-uspace_2.7.14, axis sim runs ok

Had to manually build and install mesflash.....that's good now

Now The fun part.....
To get hm2_eth to load without any errors I had to do the following......this is just a rough explanation without any instructions.

Get Mint to load the kernel modules ip_tables & iptable_filter on boot
Had to change the permissions of sysctl & iptables so they run as root.......I'm not exactly happy with this solution, but should be ok if you are the only with access to the machine and net access can be limited (this is paranoia speaking)

But after those changes I was able to test connect to my 7i92 board, I haven't got it connected up yet, just going thru a testing phase to get used to it, rather than going the "whole hog" having to fix 1000 issues at once.

That sounds promising, only time net access is for eventual updates/upgrades nothing else.
