Can anybody explain what this kind of messages in dmesg really mean, or point me to some documentation? I have failed to find non-prehistoric info about dealing with such events.
Sometimes programs seem to work just fine (both examples here) and sometimes they crash. With VirtualBox whole screen freeze (I was able to shutdown my system using the hardware power button.).
