In the console there was an additional information, which was not stored in

For bug reports like this, it's generally more useful to attach the output from
the "dmesg" command rather than copying the system log file or the contents of
the console directly into the text of the report.
Also, when tracking down problems in the kernel, it helps to build your kernel
with CONFIG_FRAME_POINTER enabled.
Why are you running hald-addon-stor? hal has been obsolete for some time.

hal was probably installed by my distribution Debian/testing.
it's installation was forced by gnome-volume-manager
also the libthunar-vfs-1-2 requires libhal-storage1 package
and libwine requires libhal
So it seems, that I can't get rid of hal.

Whether you have hal or not does not really matter. More recent userland
without hal but with udisks-daemon triggers an oops at unplug of
removable-media drives too. This is meant to be addressed by the patch from
comment 4.

I hit the same (?) bug, but without modifying the partition table:

This bug should have been fixed between v3.3-rc7 and v3.3 by commit
fe316bf2d5847bc5dd975668671a7b1067603bc7 and
9f53d2fe815b4011ff930a7b6db98385d45faa68.
