This alioth.debian.org was refusing connections for some time.
Today I have tried:
I have put that into a "ums_realta,patch" and then:
apt-get source linux-2.6
cd linux-2.6-3.2.2/
patch -p1 < ../ums_realtak.patch
fakeroot debian/rules source
fakeroot make -f debian/rules.gen binary-arch_i386_none_686_pae
2 hours later I got the linux-image-3.2.0-1-686-pae_3.2.2-1_i386.deb and installed
it via dpkg.
Unfortunately I still get a full freeze, s. typescript.after-ums_realtek.patch
I have looked around a bit myself and found:
https://bugzilla.kernel.org/show_bug.cgi?id=42615
Bug 42615 - BUG: scheduling while atomic: swapper
Maybe it's this bug?
