I've created a file '/etc/sysconfig/hardware/config-ccw-0.0.0a00' with:

After loading the ctc module, a hwup ccw 0.0.0a00 works fine.
The ctc module is loaded. I have it in /etc/modules.
A manual 'hwup ccw 0.0.0a00' does indeed do the trick.
The problem seems to be that loading the ctc module does not trigger the

Exactly.
But there is another problem left: A race condition happens if

Have we seen this in practice?
Because of the way the CTC driver is structured, one address is input
and one is output if you're speaking IP over it. It's not like using
CTC for RSCS where each address is bidirectional. So if only one of the
pair is there, I'd say that it's broken and you

*I* always use the even address as the bottom one of the pair.
Is there anything mandating that that has to be the case?
