SRU justification for linux-firmware for Jaunty (applies to linux-firmware-nonfree for karmic, but I believe it's not necessary because the -nonfree package resides in multiverse):
Impact: The current package ships with corrupt firmware for Hauppauge HVR-4000 tuner cards. The firmware does not pose a physical device hazard, but usage of the device is prevented by the corrupt firmware. When the correct firmware is used the device works properly
Addressed: The latest linux-firmware-nonfree package (which was split from linux-firmware in Karmic) for Lucid version 1.7 replaces the incorrect firmware with the correct firmware, verified by md5sum against the firmware listed in [1]. However, this firmware is incompatible with the kernel shipping in Jaunty and Karmic. Thus, a previous version of the firmware has been used, verified again by md5sum against the firmware listed in [1].
Minimal Patch: Change is not diff'able. The dvb-fe-cx24116.fw file was replaced with a fixed version.
Reproduction: Load the v4l-dvb drivers on a machine with affected hardware. Drivers will fail to load the firmware because it is corrupted. Device will fail to work properly.
Regression Potential: Minimal because this change merely replaces one broken firmware file with another. Worst-case scenario is people still fail to use their devices due to incorrect firmware.
