6 days ago I did a usual "apt-get update && apt-get upgrade" which brought up the following output:

rock@rock-3a:~$

 

After a reboot the USB port bus 007:device 002 on with an Arduino Nano connected

 

rock@rock-3a:~$ lsusb 
>>> Bus 007 Device 002: ID 2341:0043 Arduino SA Uno R3 (CDC ACM) <<<
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

 

does not show up anymore as '/dev/ttyACM0' !

Although the device does exist:

rock@rock-3a:~$ ll /dev/bus/usb/007/002 
0 crw-rw-r-- 1 root root 189, 769 22. Okt 12:40 /dev/bus/usb/007/002

 

And therefore is no more accessible.

Multiple reboots did not resolve the problem.

 

What to do now? I do appreciate any idea 🙂

Thx for helping!

removed some lines of irrelevant code output

This is how mainline Linux looks like. Features breaks all the time (caused by constant kernel changes / development) and its impossible to track as this is simply too expensive. Linux distributions in majority are not doing any testings of those functions, while our test system is too primitive to detect something like this. A few more hundreds of thousands would be needed to put in, which is, in case you want free service, impossible. If detection would be made, someone needs to invest hours to fix it. Currently waiting things, average resolving rate = 400 days. So you have an idea how little you are investing into maintenance on top and around chaotic mainline Linux experience.

Workaround? Those usually always exists. One of them is going to armbian-config -> system -> other kernels and switch to older kernel, where this function was working. Then freeze kernel (which is anyway good thing for production deployment) and check from time to time if this was fixes. No, nobody will send you email when this will be fixed ...

Further investigation gives, that the running kernel (like already written in the title) is still "Linux rock-3a 5.19.10-rk35xx" whereas the updates installed the version 5.19.14:

I already installed a newer update (5.19.16-rk35xx) but still the 5.19.10-Kernel is active, regardless of any reboots.

 

The name/version of the subdir in /usr/lib/modules/ gives the correct installed version (latest is .16) and unfortunately a symlink to it does not resolve the problem:

rock@rock-3a:/usr/lib/modules$ ll
0 lrwxrwxrwx  1 root root   14 22. Okt 21:49 5.19.10-rk35xx -> 5.19.16-rk35xx
4 drwxr-xr-x  3 root root 4096 22. Okt 22:04 5.19.16-rk35xx

 

My question for now is: Where is that old initrd-image from which the kernel is loaded?

How could it load if already removed by the update process (see first log)?

 

And why is it installing "linux-image-edge-rk35xx" instead of a "stable" version? If I wanna have an "on-the-egde"-kernel then I expect do have a switch somewhere to activate it but not to have the latest "egde"-version as a default option. Am I too naive to think that way?!?
