  1. Hi, I know at least some distributions don't remove modules of currently running kernels. Even when upgrading kernels and modules. Also, armbian has files like /etc/apt/apt.conf.d/01autoremove etc, which look like they're meant to accomplish the same (protect selected kernel modules from removal), but have in fact no effect (by default). How can I prevent removal of files on upgrade (specifically, kernel modules)? That is, enable the /etc/apt/apt.conf.d/01autoremove and related things to have an effect, or set some other option to do something similar. Actually, I would also prefer to keep a few previous kernels and support files (the files in /boot). Just what some other distributions do by default. thanks

    Orange Pi i96

    Hi, I have an orangepi i96 (without the 2G). In theory, it would be a great board that performs some task (GPIO), connects with wifi, uses commodity accessories (USB power, serial) and is very cost effective at that (is it?). However, wifi seems to be the problem (not only for me). It acts really unusual. So I got some image, long ago, /etc/issue says it's not armbian but raspbian. Kernel is a ... you guessed it ... 3.10.62. First problem is serial, one has to know that the rate is 921600. I think I had one type of dongle that wouldn't work, and another one that works (both 3.3v). A command like "screen /dev/ttyUSB0 921600" will connect. However, after longer sessions the connection will be garbled sometimes. Once it still remained garbled after reboot, power cycling etc. - maybe it must cool down? Anyway, that would be only temporary. Real problem is wifi. At times I got it to work by holding it by its antenna. Letting the antenna go made it stop working. Really. But at other times that is not sufficient, and in one situation it was not required. The wifi behaviour depended on: Power supply. USB 5V 1A plug was worst, 5V 2.1A plug was better, USB Quickcharge maybe even better, but my laptop's dock seemed to be best. But it would only be usable with its own plug. Connecting a DHT11 sensor to GPIO made Wifi almost completely unusable in all situations. Connecting a non-working little USB Wifi dongle (there are no drivers for it on the image) made the built-in USB work with both laptop dock power supply and 2.1A plug. (but only without DHT11 sensor) Disconnecting the USB/serial dongle is untested. So the wifi _software_ seems to work fine, but there seem to be electrical problems with it. How is your experience with wifi on this one? Are there devices where wifi "always" works, or some where it does not work at all? Did you get similar crazy behaviour like me? Could there be some driver update that magically solves all the problems? Does wifi work if the USB/serial is removed? (For me it is hard to tell, due to the lack of a fixed mac address and extreme boot times ...) I guess it does not. Ethernet adapters also don't work, due to lack of drivers. thanks
