Bonjour, I wanted to install alsa, so : "yum install *alsa*" fetch the headers.... solving dependencies.... unable to install: /lib/modules/xxx.2179nptlxxx is missing!!! I never had any kernel 2179nptl!!! Why yum doesn't test which is the running kernel whenever it has some modules to install? I think that I had to put the "*" because there so many packages with alsa in their names.
