Hello everyone first post in these forums and very green to Linux. Anyway this is the problem that I'm having updated my fedora core 4 to the lasted kernel with yum, and now my nic card is not working. I have read some where that the latest kernel is having problem with some nic cards. I just want to know how to go back to the previous kernel that I had on my rig. In terminal what do a type to see my version I have right know and what do I type to go back to the previous version that I had. Thanks in advance for any input on this .
