RE: [Xen-users] 3.4-testing : Kernel panic on bootup (mount: couldnotfin
Look at your grub config.
Root=/LABEL=/ looks way wrong.
It should point to something in the /dev directory.
In my case my hard drive that has the / file system on it is /dev/sdc1
Look at your other grub configs for your other WORKING kernels and make the
root=/ section of your grub config the same as what those kernels read.
