[Christian Kujau]

Package: iscsitarget-dkms
Version: 1.4.20.2-11
Severity: important

Installing iscsitarget-dkms tries to compile the iscsitarget module. This fails for the installed
kernel linux-image-3.6-trunk-amd64 with the following message from
/var/lib/dkms/iscsitarget/1.4.20.2/build/make.log:
