i keep updating fedora with yum. it updated my kernel but there were no updates for nvidia or ntfs kernel modules. so i stayed with the kernel-smp-2.6.11-1.27_FC3 release instead of moving onto the kernel-smp-2.6.11-1.35_FC3. Then they delivered an "upgrade" for the 27 version security module selinux. This prevented my system from booting as security was too tight. So I had to boot into the newer kernel which luckily worked but had to use the VESA drivers. Had to wait ages for the nvidia drivers. But anyway the volume control applet has just stopped working (in the 27 and 35 releases).
Surely someone at fedora must test the most basic functions of the OS (like the volume control) before upgrading the whole kernel? I would like to get more into reporting these bugs myself but with something this basic it seems staggering!
