In most cases the problem occurs when switching from X to a text console, which renders the keyboard totally unusable. Pressing any key results in ^W ^E and other garbage. Sometimes pressing Ctrl fixes the problem, other times not even SysRq works. The kernel logs the following stuff: keyboard: unrecognized scancode (70) - ignored keyboard: unrecognized scancode (66) - ignored keyboard: unknown scancode e0 71 keyboard: unknown scancode e0 70 and so forth. I cannot reliably reproduce it though. Can someone enlighten me whether this is a keyboard problem, X problem or something wrong with the kernel's console stuff? -Udo. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
