Hello I m using Fedora 7 Test 2. Two kernels are installed : 2.6.20-1.2981 and 2982. The 2982 doesn't boot, there is an oops during boot. So I continued to use the 2981. From time to time, kernel freezes, so I wanted to update to the 2987 version. The problem is that during the install, I get another crash. At reboot, there s still 2981 & 2982 kernels in grub menu, but rpm -qa | grep kernel tells me that 2987 is installed. What is the best to "clean" the system, and to reinstall the 2987 kernel ? Thanks in advance. Axel
