The lirc_dev module contained in the dkms-lirc package shipped with Mandriva Linux 2009 contains a bug which would cause it to crash immediately on load. The result of this is that lirc is unusable, and if you have dkms-lirc installed and the "lircd" service enabled, the system may fail to boot correctly. The updated package fixes this bug and provides a set of lirc modules that load and work correctly. Please note that this issue only affects systems with the actual IR hardware that lirc works with.
