** Description changed:
+ SRU justification:
+
+ Impact: One of the updates from 2.6.28.10 for unknown reasons messed up
+ the backport of the patch from upstream, placing some code at the wrong
+ place which causes an Oops as soon as the module is loaded and the
+ hardware gets probed.
+
+ Fix: Move the code section to the same place the upstream patch had
+ intended the code to go.
+
+ Testcase: Plugging in the Gigaset ISDN hardware, which causes the module
+ to be loaded and the hardware to be probed (fix verified by reporter).
+

Binary package hint: linux-image-2.6.28-15-generic
Ubuntu: 9.04 64bit
Since upgrading to the regular 2.6.28-15 kernel, there's an error when
connecting a gigaset ISDN phone via USB:

This prevents the system from shutting down, hibernating or going to standby
properly. If a type "lsusb" the shell hangs forever.
Up to the previous kernel (linux-image-2.6.28-15-generic), everything worked
fine. When plugging the usb phone connection, there was:
