I had a system where the rpm command was very slow after I was trying to upgrade a package
root@rhel5:~ # rpm -Uvh /tmp/kexec-tools-1.102pre-154.el5.x86_64.rpm
error: failed to stat /media: Input/output error

The filesystem /media is a NFS share. The server that was hosting the NFS was down and the rpm command was slow because it tried to stat the filesystem.
