Description of problem: openib-perftest and perftest obsolete each other, without any versioning informatiion. This causes a whole bunch of problems, like "yum update" will continue forever installing the other package ... the worst of which is that "yum install perftest" doesn't work. The sane fix is to remove the obsolete from one of them (and make the other version specific, i.e. in perftest Obsoletes: openib-perftest <= 1.2-5.el5_1.1). Version-Release number of selected component (if applicable): openib-perftest.i386 1.2-6.el5_1.1 perftest.i386 1.2-10.el5 Additional info: I've done a patch against the 5.2.z yum which "fixes" the biggest problem (recursion traceback so you can't install either): http://people.redhat.com/jantill/yum/patches/yum-obs-loops-install.patch ...but all the others are basically unfixable, in that there's no "right" behaviour that yum can guess correctly.
