Neither */var/log/kern.log* nor */var/crash* contains anything useful. When it happens it's like it went into a NOP-loop, everything freezes (including mouse pointer) and it reacts to nothing until power cut or reset. I wasn't able to find any steps to reproduce it, it seems fully random. Kernel 4.15.0-58 works fine.
