I have no problem installing fedora 9, but I can only boot into kernel 2.6.25; Upgrading to kernel 2.6.26 / 2.6.27 results in a hang at "remounting root filesystem read-write" while booting. Neither can I automatically upgrade to fedora 10 using preupgrade (hangs right after booting into the upgrade grub entry).

So since everything works with kernel 2.6.25, this is more likely to be a kernel driver error, I assume?
