Kernel debugging with Kprobes

Anonymous Reader writes “Collecting debugging information from the Linuxâ„¢ kernel using printk is a well-known method — and with Kprobes, it can be done without the need to constantly reboot and rebuild the kernel. Kprobes, in combination with 2.6 kernels, provides a lightweight, non-disruptive, and powerful mechanism to insert printk’s dynamically. Logging debug info such as the kernel stack trace, kernel data structures, and registers has never been so easy!”
