I'm having the very same problem. When I attempt to boot from the newly installed kernel, "vmlinuz-2.6.31-14-generic," I get dropped into a character-mode console, which apparently runs from the initial ram disk --the prompt is "(initramfs)".
The previously installed kernel, "vmlinuz-2.6.31-13-generic," continues to work fine. Together with the generic kernel, the real-time kernel (which is also installed on this karmic system partition) got updated as well--from "vmlinuz-2.6.31-7-rt" to "vmlinuz-2.6.31-9-rt". In contrast to the updated generic kernel, the new real-time kernel boots up fine; in fact, I'm running it as I type this comment. I'm attaching the text that I see when I try to boot the "vmlinuz-2.6.31-14-generic" kernel. (I typed the text over manually, so I hope I didn't introduce any typos in the text.) The output from the "sudo blkid -p /dev/sdc2" is as follows (I executed the command while running the newly installed--working--real-time kernel): /dev/sdc2: UUID="4034c660-0e15-48f5-8b9a-128b5b0861ed" VERSION="1.0" TYPE="ext3" USAGE="filesystem" ** Attachment added: "Kernel 2.6.31-14-generic Boot Failure.txt" http://launchpadlibrarian.net/33912010/Kernel%202.6.31-14-generic%20Boot%20Failure.txt -- grub misconfigured after upgrade to linux-image-2.6.31-14-generic https://bugs.launchpad.net/bugs/454418 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
