Hi Martin
The ccw devices currently don't have a modalias spec in sysfs. This
makes it impossible to ask udev for loading the modules.
Are there any patches pending?

Hmm, never heard of modalias. Arnd has done the module loading for ccw
devices. That must be something rather new.

No, but as far as I can tell after glancing at the modalias
implementation in usb this would make sense for ccw as well.

Yes, it is rather new.

Hmm, I don't find device tables in ctc.ko and lcs.ko, can that be fixed
at the same time?
Hmm, something else. Wasn't there a cu type or device type clash between
escon and lcs, or was that only related to chan types reported by the
2.4 kernels?

That is because ctc and lcs are group device drivers. The ccw device
driver is the cu3088 driver. You'll get an lcs/ctc device by "grouping"
two of the cu3088 device together.

Yes, the 2.6 group devices have emerged from the 2.4 chandev devices
(and thank god that we got rid of that junk).

Okay. But should work anyway.
I implemented it half through, will test that tomorrow.
