tag 566632 + patch
thanks

The following (simpler and cleaner) change in hwup-ccw-group also fixes the 
issue:

-ccw=/bus/ccw/drivers/$NAME
+ccw=/bus/ccw/devices/$ID/driver
 ccwgroup=/bus/ccwgroup/drivers/$DRIVER

Bug#566632: sysconfig-hardware: Fails to bring up ctc network interface with kernel 2.6.33-rc5

[Frans Pop]

Package: sysconfig-hardware
Version: 0.0.9+nmu1
Severity: important

Due to a change in the kernel for 2.6.33, my CTC network interface is no
longer brought up.

Reason is that the value of the DRIVER sysfs value for the channels has
changed:
2.6.32:
$ grep DRIVER /sys/bus/ccw/devices/0.0.0a*/uevent
/sys/bus/ccw/devices/0.0.0a00/uevent:DRIVER=cu3088
/sys/bus/ccw/devices/0.0.0a01/uevent:DRIVER=cu3088

2.6.33:
$ grep DRIVER /sys/bus/ccw/devices/0.0.0a*/uevent
/sys/bus/ccw/devices/0.0.0a00/uevent:DRIVER=ctcm
/sys/bus/ccw/devices/0.0.0a01/uevent:DRIVER=ctcm

This means that also a directory used by sysconfig-hardware has changed:
/sys/bus/ccw/drivers/cu3088/ => /sys/bus/ccw/drivers/ctcm/

I've worked around this by making the following change in hwup-ccw-group
(with backwards compatibility preserved):
 if [ "$name" == cu3088 ]; then
   modprobe ctcm 2> /dev/null || :
   modprobe ctc 2> /dev/null || :

   if [ -d $SYSFS/module/ctcm ]; then
 DRIVER=ctcm
   elif [ -d $SYSFS/module/ctc ]; then
 DRIVER=ctc
   else
 error "no kernel module for ctc devices available!"
   fi
+
+  # Identification of driver changed from 'cu3088' to 'ctcm' in 2.6.33
+  if [ ! -d $SYSFS/bus/ccw/drivers/$NAME ] && [ -d $SYSFS/bus/ccw/drivers/ctcm 
]; then
+NAME=ctcm
+  fi
 elif [ "$name" == qeth ]; then

But possibly a cleaner solution is possible.
