Because that is quite a complex task on a modern graphics card. Usually there is no way to switch to a mode (be it text or graphics) without knowing the current mode, and that information is only present in the X server, not in the kernel. And since the kernel is in panic, the X server can not run and can not do the mode switch. I think there are patches to print panic messages to the frame buffer if it is in use; but that still requires the X server to be configured to use the kernel-provided frame buffer, and that can be quite slow (and it also has other problems like not working on dual-head setups etc.) Gabor -- --------------------------------------------------------- MTA SZTAKI Computer and Automation Research Institute Hungarian Academy of Sciences --------------------------------------------------------- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
