This is correct. I have double-checked 3.2.54-2:

Unfortunately, the crash is still there, followed by several more
errors in the log (attached).
The kernel was rebuilt and reinstalled as follows:
cd src/linux-debian/linux-3.2.57
rm debian/patches/test/rtl8192ce-fix-null-dereference-in-watchdog.patch
bash debian/bin/test-patches -j 8
~/Downloads/revert-rtlwifi-rtl8192ce-fix-too-long-disable-of-irqs.patch
sudo dpkg -i ../linux-image-3.2.0-4-amd64_3.2.57-2a~test_amd64.deb
sudo reboot
--
...Bye..Dmitry.
