Description of problem: In Fedora 9, networking broke after upgrade of kernel from 2.6.25-14.fc9 to 2.6.25.3-18.fc9. The older kernel "just worked" and loaded the e100 driver automatically. The new kernel does not include e100.ko, and no alternate is (obviously) available. Version-Release number of selected component (if applicable): kernel-2.6.25.3-18.fc9.i686
The file /lib/modules/2.6.25.3-18.fc9.i686/kernel/drivers/net/e100.ko does exist in a proper installation. Check rpm -V kernel and that the file is there. If it is, does "modprobe e100" give any errors, or messages in dmesg?
Sorry - that's something I should have checked. Yes, rpm -V shows that lots of files are missing. I'm not sure what happened. I jumped to conclusions because the problem showed up right after the "yum update" and there were no obvious problems or errors in the update process. It seems like there still may be a bug buried here somewhere, but it's not this one. Never mind!
