Problems updating the to the last kernel

[José Matos]

Hi,
	since Saturday I noticed that the update of kernel takes a long time, I 
noticed that grubby was running for more than 2 and a half hours. :-(

	I killed grubby and the installation of other packages proceeded normally.

	Now everytime that I try to update the kernel grubby takes forever and never 
updates /etc/grub.conf. :-(

	As an example the command being executed by rpm scripts is:
# cat /proc/5860/cmdline
/sbin/grubby--add-kernel=/boot/vmlinuz-2.6.21-1.3226.fc7--initrd/boot/initrd-2.6.21-1.3226.fc7.img--copy-default--make-default--titleFedora 
(2.6.21-1.3226.fc7)--args=root=/dev/VolGroup00/LogVol00 --remove-kernel=TITLE=Fedora 
(2.6.21-1.3226.fc7)

  I had killed it after running at almost 100% CPU during an hour.

  Clearly this is not normal, what could it be the culprit?

PS: Note (as it can be seen from attempt to install the kernel) that I have 
DaveJ's repository configured for yum.
