Hi,
I have update the kernel to kernel-2.6.24.7-92.fc8
now I cant boot up but I can boot older kernels
I get the error message cant find directory /dev/root
cant mount /sys ....
I have seen other people get this error but they had change hdd to other pc I didnt change any hardware I just updated the kernel using yum
I also tried reinstalling the kernel again using now and I downloaded it as rpm same problem in both cases.

Thank You.

Did you check the entry for the new kernel in /boot/grub/menu.lst?
