cio.0f6270 No CCW console was found
Explanation
Linux did not find the expected CCW console and tries to use an alternative
console. A possible reason why the console was not found is that the console
has been specified in the cio_ignore list.
User response
None, if an appropriate alternative console has been found, and you want
to use this alternative console. If you want to use the CCW console, ensure
that is not specified in the cio_ignore list, explicitly specify the console
with the 'condev=' kernel parameter, and reboot Linux.
