Yes Nikla, off course thats right. But I am very glad to have such a nice alternative OS like OI and errors and bugs are accepted.
However it's crazy that the same thing happened today on a second machine. OK, the hardware was nearly identically (older Asus F2A85 board mit amdgpu, A10 processor, 32 GB of RAM and SATA and Nvme ssds. Today I could fix it very fast.
Thanks again for your kind assistance.
