It does appear the problem I was seeing was the mkinitrd problem and that it can be worked around be keeping a 2.6.24 kernel around until the problem is fixed. What I did to test this was: boot kernel-2.6.25-0.35.rc1.fc9.i586 uninstall kernel-2.6.25-0.40.rc1.git2.fc9.i686 reinstall kernel-2.6.25-0.40.rc1.git2.fc9.i686 Test booting kernel-2.6.25-0.40.rc1.git2.fc9.i686 -- it failed boot kernel-2.6.24.1-31.fc9.i586 uninstall kernel-2.6.25-0.40.rc1.git2.fc9.i686 reinstall kernel-2.6.25-0.40.rc1.git2.fc9.i686 Test booting kernel-2.6.25-0.40.rc1.git2.fc9.i686 -- it succeeded -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
