Unable to boot after using Genkernel
Hey everyone,
After unnecessarily adjusting my kernel:( which is the most up to date version in sabayon x86/64 with Genkernel my system of coarse had to crash:rolleyes: so I didnt really get a chance to follow the directions on how to copy or mount anything to the bootloader. Can anyone tell me what this means and how to fix it? It begins printing right after all of my modules load. >>Activating Mdev !!vgscan or vgchange not found: skipping LVM2 volume group activation! ln:/etc/splash/suspend2: no such file or directory >>Determining root device... !!Block device /dev/volGroup00/ LogVol00 is not a valid root device... !!The root block device is unspecified or not detected Please specify a device to boot, or "shell" for a shell.. boot():: |

I can't really know what your root device is, but you could try some of the following: /dev/hda1 /dev/hda2 /dev/hdb1 /dev/sda1 .... The 'hd' is for an IDE drive, a, b, or even c or d are for primary master, primary slave, etc. The number is the number of your partition. 'sd' stands for special device I believe (don't take my word for it). You get this if you have SATA. Again letters and numbers are used for subsequent devices and partitions. |
I've not used Sabayon, or even genkernel under gentoo, but I'd be willing to bet you need an initrd. You're not going to be able to see your data without LVM active.
Go back in and boot your old kernel and fix up menu.lst |
As a matter of fact sygOO ur right! I remember the terminal message telling me to adjust or either save INITRAMFS to the boot record.
After entering boot()::/dev/sda1/ I get the output of >>mounting root... mknod:/newroot/dev/console: No such file or directory mknod:/newroot/dev/tty1: No such file or directory >>Booting(initramfs)..switch_root:Bad console'/dev/console' [ 86.717681] Kernel Panic-not syncing: Attempted to kill init! so how do i reinstall my old kernel to fix this? THX:newbie: |

Given that is a gentoo base, I expect you could boot the DVD, chroot into your disk install and re-emerge sabayon-sources. Seems to be a reasonable guide on their wiki for genkernel. |
"...attempted to kill init..." is a scream for extras parameters for the Kernel to be booted correctly. During boot up there are choices to be read and/or chosen. Something along the lines of..."gentoo acpi=off doscsi noapic " will get the boot started. Please keep in mind, each system could require different parameters <cheat codes>.
