The system just reboots. oooh.. so you dont KNOW its a kernel panic... you don't have a serial console? you should get one :) > I think that classifies as "ecore_fb not handling the vanishing of the > device properly" though. well it may not handle the error case for reading the device as nicely as it should - eg close it and clean up. it may keep it open, which may TRIGGER a kernel bug, but thats still a kernel bug to be fixed in the kernel, if it is a panic. > This linux system is one I'm building from scratch, just enough so far > to let me run elementary_test in fb mode.
