I'm running FC4 on an HP Compaq nx9110. I have three different kernels installed. 2.6.11-1.1369_FC4smp has always run fine and is what I'm running now. Using yum update on occasion has installed two other kernels: 2.6.13-1.1526_FC4smp 2.6.13-1.1532_FC4smp Problem is I can't run ether of these. They won't even boot, or they are going so slowly you think it's not doing anything. They both get stuck at the Starting udev.... prompt. The original kernel whips by that point in no time. I had the problem with 1526 for a while and figured I'd wait til the next kernel came out. This morning 1532 got installed and it has the same problem. I know I haven't really given much information about this but wondering if anyone else has seen this before. Sorry if it's been discussed a hundred times already. Did not find much googling. Thanks, James
