It talks about some changes that weren't carried through to the newest kernel, that of timing issues with the Realtek devices. I assume that's the same whispers I saw regarding timing elsewhere.

https://forum.armbian.com/topic/9402-eth...ne-module/

I'm out of my league at the moment doing kernel recompiles, but I'll try and provide any information that is needed to get this resolved.


(edit: I tried to post my findings in the Armbian forum, but I've forgotten my password and the email reset appears to be broken...)

That is the exact issue you are fighting against.  You can fix it on the newer kernels - one module at a time - by modifying one of the boot files as described in that other thread.  But it requires a serial console and is a PITA.

I appreciate all the work that Armbian does, but there really is no excuse for this issue remaining open and untouched by them for this long.

Once you get past that one the next hurdle to get over is the "won't reboot without power cycle, which required power cycling the whole cluster" issue.  This one really needs to get fixed if the Clusterboard is ever going to be really useful.  At is is mine is back on a storage shelf because its just not worth fighting it.

In fact, if anyone wants a Clusterboard and 8 so-pines at a good discount you could PM me...

The Armbian people are supporting a lot of boards. Too many perhaps, although I assume a lot of code gets reused. And I wondered about the reboot thing, I was able to get some to work ok rebooting and some did not. I didn't realize that was yet another problem. I'm just confused as to why the baseboard works fine as opposed to the clusterboard. I may try the console fixes...

I kind of wish they'd put 7 Ethernet jacks on the thing instead of using the switch, like some of the (sadly, prototype only) Pi Clusters used. That might solve some of the issue. I don't know, perhaps the Ethernet could be broken out to jacks instead of the switch.  I'm going to suggest that to Pine, at least provide headers and a way to turn the switch off. Should be easy enough to get some magjacks and get the switch chip off there.

PM me what you'd want for your cluster set and what country you're in (shipping is nasty...) I'll see if I can afford it, I'd like to have some of these to play with in my own layout.
