Once I commented it out, it was gone. Interestingly, I couldn't provoke this bug in my VirtualBox, but only when I tried to test it on my main installation. I don't have a "drm" device in VirtualBox, though. The string "drm", it tries to log, comes from devclass_get_name(). I suppose this string has static lifetime - it shouldn't be possible to become invalid. And in fact, the double fault is obviously caused long after the string has been read. Best regards, Robin
