Printk has served as an archaic debugging tool for the Linux kernel since the dawn of time. However it was always a bit limited by syslog not being able to store the last dying breath of a crashed system and VGA consoles display little more than 80x25 - provided you actually see the output an can find your camera in time to capture it. This presentation goes through a number of tools that have made printk more useful in an environment with hundreds of machine running automated tests and more than enough developers creating new and exciting bugs for motivation.


Joern Engel

Pure Storage
Joern currently works for Pure Storage, and mainly deals with bugs and performance problems in various parts of the Linux kernel's storage stack. Previously he has been best known for creating LogFS.
