The kernel backports are nearly finished and so its time to test on as much hardware as possible.
Please report all working and not working hardware on the compatibility lists on the wiki .
The internal data of the pakfire packets will now be compressed with xz to save download bandwidth. This needs a change in pakfire. You should reinstall the latest 2.13 build to get this feature and the newest kernel as well.
If you really need to use an older build, you have to change /opt/pakfire/lib/functions.sh to be able to install new pakfire packets.
