I upgrade kernel from 2.6.27 to 2.6.27.2 on Fedora 10 beta, but the
system won't boot with the new kernel. The system can still be booted
with the old one. The /boot/grub/menu.lst has the new and the old
entries as following. I use the same UUID as the one used for 2.6.27
for 2.6.27.2. This may be the problem, but I don't know how to get a
new UUID or do I need a new one.
# /boot/grub/menu.lst
title Fedora (2.6.27.2)
root (hd0,0)
kernel /vmlinuz-2.6.27.2 ro root=UUID=184eb91e-
e8f3-4812-8814-9e57f9b02a33 rhgb quiet
initrd /initrd-2.6.27.2.img
title Fedora (2.6.27-0.352.rc7.git1.fc10.i686)
root (hd0,0)
kernel /vmlinuz-2.6.27-0.352.rc7.git1.fc10.i686 ro
root=UUID=184eb91e-e8f3-4812-8814-9e57f9b02a33 rhgb quiet
initrd /initrd-2.6.27-0.352.rc7.git1.fc10.i686.img
# /boot/grub/menu.lst ends
The new kernel image has been generated. More information below. I
hope this is enough for you to diagnose my problem : ) Thanks!
