Comment 1 for bug 284863

Hi,

I'm also getting exactly the same error in Ubuntu 8.10 after upgrading to kernel 2.6.27-9.

Steps to reproduce:

sudo apt-get install exmap exmap-modules-source
cd /usr/src
sudo tar xvzf exmap.tar.gz
cd modules/exmap
sudo make

make -C /lib/modules/2.6.27-9-generic/build M=/usr/src/modules/exmap modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.27-9-generic'
