I am running FC3 on an IBM T42 laptop. Early this morning I was running system-config-network to change some network settings. The system- config-network app became very erratic in it behavior so I had to kill its process. I next rebooted my machine (normaly less that a 1 minute process) and it took 19 minutes to reboot. After many hours of searching I found that I had a corrupted /etc/modprobe.conf file. I was 185 MB in size and full of gibberish. My question is how can I regenerate a correct modprobe.conf file for my machine? Can I simply reinstall the package that creates it? (rpm -q --whatprovides /etc/modprobe.conf does not return anything), Are there scripts in place that recreate the file? (I did try running /sbin/generate-modprobe.conf but all it seems to want to do is convert a modules.conf file to a modprobe.conf file). Thanks in advance for any help that you can provide. Charlie
