-**Kernel printk log level**:FIXME
+**Kernel printk log level**: controls the detail level of kernel messages printed to the console and log buffer via the printk() function
- \\
+Kernel messages use numeric levels. Lower numbers indicate higher priority: 0 (KERN_EMERG) for system crashes, 3 (KERN_ERR) for errors, 6 (KERN_INFO) for general info, and 7 (KERN_DEBUG) for detailed debugging. Setting a higher value or 7 or 8 in "/proc/sys/kernel/printk" allows more messages, including debug output, to print immediately to the console rather than just the ring buffer viewable via dmesg.\\
