yum upgrade F7-f8 dependency check never ending(loop)

[zhu blue]

Hi,
for my F7 system, after I run "yum update"/"yum clean all", then I issue
the following command:

#rpm -Uhv
http://mirror.anl.gov/pub/fedora/linux/releases/8/Fedora/i386/os/Packages/fedora-release-8-3.noarch.rpm  http://mirror.anl.gov/pub/fedora/linux/releases/8/Fedora/i386/os/Packages/fedora-release-notes-8.0.0-3.noarch.rpm

which succeed.

but when I issue the followng command again:
----------------------- 
#yum -y update
-----------------------
after sometime, the dependency check never end, I looked at the out put
message closely , found that it enters a loop as following:
