If the following config option is set, I can't get traces. If I unset it, I can't get mouse or keyboard. Do you have a work around or a patch for this ?
# CONFIG_SERIO_I8042 is not set => the trace stop and keyboard works. CONFIG_SERIO_I8042=y => the trace is ok but no keyboard and mouse.
If the system is loaded and you can type something, an echo x >/dev/ttyS0 fixes the problem. You can have new traces. The problem is still between the i8042 loading module and the system ok to works : If you have a module loading problem or something else, you can't get trace. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
