Linux alarm 4.18.5

This is exactly my first recommendation. Check our DEV, which is 4.18.5 ... 4.14.y has some issues which we are trying to find and fix.

But if you give me the commands

I have no idea how this system was put together. We support Armbian, not hardware. The serial console costs 2USD and would save us a lot of time.

I could easily crash 4.14.y on Orangepi PC+ ... so it's clearly something wrong with this kernel. Debugging ...

@AlbertB Try attached kernel & dtb (dpkg -i *.deb). I think/hope problem is fixed.

linux-dtb-next-sunxi_5.59_armhf.deb

linux-image-next-sunxi_5.59_armhf.deb

@Igor Instructions unclear.

What shall I do with the deb files? Do I have to replace something on the SD-card after writing the "mainline kernel 4.14.y or 4.17.y Image" with etcher?

 

In a SSH session, upload those files on the board using "wget <url_above>" one at a time, than do "dpkg -i <uploaded_files>" ...

 

The cubietruck froze during

root@cubietruck:~# dpkg -i *.deb

I'll give it another try later.

Regarding the serial console adaptor: can you recommend my anything or will such a thing form ebay do the job just fine?

Probably. I am using  those from:

Also, this seller is trustworthy.

It froze for me once ... then when I tried to catch some info ... I made an extensive stress test, compiling a kernel and installing various things all at once ... it didn't want to freeze again in 24h. Strange.
