Hi

This is a GRUB bug that we've been unable to reproduce reliably, and therefore haven't traced fully. It's often triggered by using the grub --once flag, which is used by both preupgrade and suspend-to-disk (hibernate). We've seen it happen with both of those things, but the preupgrade case seems to be more frequent because it tends to also involve upgrading GRUB at the same time.
I've just seen this problem happen after a yum upgrade. I installed switchdesk-gui, yum updated and groupinstalled XFCE. on the next reboot I had a broken grub. Here are log excerpts showing what got updated/installed:
Could this happen just by installing a new kernel?
