Probably some borked driver or so. "dmesg" might tell you what. > 2) How can systemd know how many messasges were missed? Kernel messages delivered to userspace come with a sequence number. If there are some missing we know the kernel dropped them from the kmsg log buffer before we could read them. > 3) Can I avoid that problem? Figure out which kernel driver/subsystem is responsible. You could also enlarge the kernel log buffer, see log_buf_mem= kernel cmdline switch.
