I updated my rawhide VM today (on F15 host), but it failed to reboot using the new kernel, vmlinuz-2.6.39-0.rc1.git5.0.fc16.x86_64 I got a failure (VFS diagnostic complaining that the UUID-specified root partition was not available), then panic. Two subsequent attempts to reboot failed because even though I got to the grub kernel-selection menu, I was unable to get a response out of the interface, so couldn't select any other kernel or even edit a grub stanza. Luckily for me, on the third attempt, grub's UI did respond to down-arrow and "ENTER", so I could select the preceding kernel, and that one did manage to boot. If necessary (i.e., if it's not already fixed), I'll file a BZ. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
