Repeated and works, strange. ;)

I assume with my edits this is the sarcasm that was intended.  :)

there was no sarcasm or malice. your delusional inter-recipe. I built an armbian 5.46 bionic and xenial two images. In both there is an old mistake with the meson8b-dwmac player. simply eth0 turns off after 3-5 minutes.Fortunately, there is wifi. I do not mind. after the changes everything works de luxe. browsers and other software I use all the time from yesterday from 15 o'clock and the system has never hung up. Also, I am happy thank you for the work you have done. It's good.

Sarcasm is not the same as malice, sarcasm can be used humourously or in an ironic context.  Delusional, on the other hand, is quite negative and I do not know what "inter-recipe" is.  It is difficult at times to have so many communicating in a 2nd language, not everyone's particular "flavor" is the same.  I get caught in conversations between Japan, Hungary, France, Germany and Mexico regularly, for instance.

 

I will review this Ethernet issue you report, can you verify the kernel you are using?  Also, the driver is not a mistake, it is the proper driver.  I experienced a brief self-correcting interruption transferring a large file, but so far have not experienced the connection going down.  I will try to aggravate the failure mode.

So far the K2 has behaved for me, but obviously 1 guy may not provide an exhaustive enough test.

 

I pushed HDMI audio fixes for the Next kernel, which is currently 4.17 if anyone was getting frustrated over that.  Despite the applicable patch, DVFS is still showing me clock setting failures, it will change clock speed (according to the kernel, but we know it actually has little to no control of that), but only toggles between min and max (at least in my experience so far)

 

[edit]  I have found that I have no USB peripherals on the K2 with 4.17.  Will check into it.

 

SSH'd in: 

 dwc2 c9000000.usb: c9000000.usb supply vusb_d not found, using dummy regulator
[    2.614838] dwc2 c9000000.usb: c9000000.usb supply vusb_a not found, using dummy regulator
[    2.627851] dwc2 c9000000.usb: dwc2_check_params: Invalid parameter lpm=1

[    2.628259] dwc2 c9000000.usb: new USB bus registered, assigned bus number 1
[    2.628287] dwc2 c9000000.usb: irq 32, io mem 0xc9000000

So, everything is powered, but no one is home.

Another update, I experimentally built a 4.17.8 image today and USB is working again.  @Igor if you have the C2 it would be good to verify there as well, we should roll out new meson64-next images that work.

 

Also still getting spammed with "failed to change CPU Frequency:  -5" here.

Somebody else will need to verify this. Don't have access to this particular hardware for another two weeks.

Current Kernel 4.19 dev images appear to have a "nobody home" USB situation again (brought t0 me by @martinayotte as he works on overlays, and I verified)  Just so fewer people are surprised.  Hopefully look into this next.

 

[edit] It appears USB hot plug is the culprit, the ports have power and the hubs are brought up during boot, but the peripherals only work if plugged in before boot, not after.  I just saw this issue on Tinker Board starting with (I think) 4.17, fixed via https://github.com/armbian/build/blob/master/patch/kernel/rockchip-dev/1008-rockchip-dwc2-usb-partial-power-down.patch  (Thank you @Myy for tracking that down)

 

I'll see if that is the same issue here, have you seen anything like this, @Neil Armstrong?  I'm not seeing the issue with Le Potato, but it also has a dwc3 controller in the mix.
