Comment 30 for bug 276990

junior, the e1000e problem was due to the module writing to part of the EEPROM that it should not have been touching. The iwlagn module is fully open sourced and has been for a few kernel versions now allowing for a lot of eyes to look for any bugs. I hesitate to say there is 0 risk with bleeding edge software, but as it stands right now the only problem you may have is software based system instability at the very worst, and that can be corrected by uninstalling the module.
