Description of problem: The kernel update just pushed to f7 updates depends on
a version of mkinitrd that's not in f7 updates, so yum upgrade fails:
# yum upgrade
---> Package kernel.i686 0:2.6.21-1.3228.fc7 set to be updated
--> Processing Dependency: mkinitrd >= 6.0.9-7.1 for package: kernel
--> Finished Dependency Resolution
Error: Missing Dependency: mkinitrd >= 6.0.9-7.1 is needed by package kernel
Presumably you meant "yum update", not "yum upgrade". The mkinitrd-6.0.9-7.1
package was put in updates-testing yesterday but for some reason didn't get
pushed to updates with the kernel.
See related/dupe bug #244183 for the mkinitrd side with workaround using testing
mkinitrd-6.0.9-7.1 has been released.
