As of 3.0-rt3 the NETCONSOLE depends on !PREEMPT_RT_FULL [=y], so I couldn't enable it. I've tried to satisfy the dependencies of NETCONSOLE_DYNAMIC: Depends on: NETDEVICES [=y] && NETCONSOLE [=n] && SYSFS [=y] && CONFIGFS_FS [=y] && (NETCONSOLE [=n]!=y || CONFIGFS_FS [=y]!=m) Despite I have NETDEVICES=y, SYSFS=y, CONFIGFS_FS=y and NETCONSOLE doesn't appear in .config, it is impossible to turn on the NETCONSOLE_DYNAMIC.
