How do I install 4.17.13?

That´s great! Is the thermal sensors working? I noticed that installing the nightly builds, I lost hdd temp. Do you have a hdd and do you see the temperature?

Yes, thanks! Did I just mess up or are there no uninstallable headers for the stable version?

after: sudo apt-get install bison libbison-dev flex libfl-dev make scripts Sucsess! orangepiplus2e:~/v4l2loopback$ make VERBOSE=1 Building v4l2-loopback driver... make -C /lib/modules/`uname -r`/build M=/home/aaa/v4l2loopback modules make[1]: Entering directory '/usr/src/linux-headers-4.17.5-sunxi' Building modules, stage 2.

Ok, so I have re flashed my card. Went with: Armbian Stretch mainline kernel 4.14.y Enabled nightly builds and installed headers. So far so good. Updated. orangepiplus2e:~/v4l2loopback$ make VERBOSE=1 Building v4l2-loopback driver... make -C /lib/modules/`uname -r`/build M=/home/aaa/v4l2loopback modules make[1]: Entering directory '/usr/src/linux-headers-4.17.5-sunxi' Building modules, stage 2.

However; the only option is to switch from next to dev? This is in "Switch", should I use "Default, install desktop ..." instead?

Should I do that through armbian-config? Install headers just blink and change kernel only gives me one option that says failed, aborting. Maybe I should reinstall, might have messed up with my attempts.

Hi, trying to install or compile v4l2loopback. I fail with missing header message. I have tried armbian-config and apt-get for the headers but all fails. I have tried stable and dev. Anyone know how to do this? orangepiplus2e:/lib/modules/4.17.5-sunxi$ sudo apt-get install v4l2loopback-dkms Reading package lists... Done Building dependency tree Reading state information...

Hi, yes I have seen the remedy but it seems you loose thermal monitoring? Or you can use an older kernel. So I was wondering if the new kernel solves this. Seems like it is not?

K-worker takes 10-20 % of one cpu core with later kernels. Does the 4.17 kernel still have this problem? Or is bionic a solution?
