Created attachment 349725 [details] netconsole log Description of problem: System crashed, keyboard LEDs blinking. Version-Release number of selected component (if applicable): 2.6.31-0.33.rc1.git2.fc12.x86_64 How reproducible: Unknown Steps to Reproduce: Unknown Actual results: Crash Expected results: No crash Additional info: Something in tun maybe. People (Herbert?) were playing with tun for Xen and maybe screwed it up. Same userland works dandy with self-built 2.6.30.
