It's on Linux-kernel in the thread called "Oops/Warning report for the week of March 28th 2008" Johannes says this triggers for him: On the other hand, it should be easily reproducible by anyone else with the same trick, here's what I do: * configure X to use /dev/input/event* devices * in an xterm, do something like rmmod usbhid ; modprobe usbhid * switch to a VT * watch kernel crash as X releases the grab on the event device and I haven't tried it because none of my normal machines use modules, and I was lazy and really hoping somebody else who actually knows the device and input layers would take a peek.
