On some yum/rpm updates (with httpd, as well) this can cause the actual update to fail, but yum/rpm continues with the rest, leading to possible mis-matches and – in the case of glibc-common – to possibly a non-bootable system, if components of glibc are of different versions..

To fix this, make sure that ‘Ext3 Security Labels‘ (and Ext2 / Ext4 as needed..) is enabled when compiling your new kernel..  (under ‘File systems / Ext(n) extended attributes’)
