could be helpful to developers in order to analyse the issue. Unfortunately there are a number of scenarios where it is hard or nearly impossible to get to this data - be it because the oops happens very early during boot, or be it that the only way to get to the data is a screen shot that then needs to be transcribed. The presentation discusses a number of approaches to improve this situation, focusing on one solution that displays a 2D bar code on the display which can easily be photographed and then automatically converted back into the desired information. This talk is targeted at kernel developers but also at sysadmins and support staff. It could also be useful for application developers (as the same approach could easily be implemented in userspace).
