Unable to boot after Ubuntu 12.04 upgrade
EXT4-fs (xvda): mounted filesystem with ordered data mode. Opts: (null)
VFS: Mounted root (ext4 filesystem) readonly on device 202:0.

The graphs show that the CPU is spinning at 100% at this point, but I have no idea what it's doing.
I can't boot into the default runlevel or single user mode, but I can boot into /bin/bash and rescue mode.
My /dev/xvda is ext4 and I've tried fscking it, but it hasn't improved the situation. I've tried running with different kernels, including 3.2.1-x86_64-linode23 and the latest 3.0 provided by Linode.
Obviously 12.04 hasn't been released yet so I'm in fairly dangerous territory, but if anyone has any pointers as to how I could progress with debugging this, it would be much appreciated!

@adeb2:
Thanks for the report miknight. I was thinking of upgrading to 12.04 as well. Did you try the newer kernel already ?
Yeah I've tried all the kernels, including 3.2.1-x8664-linode23. I've been trying to get pvgrub working in the hopes of getting more info, but so far it hasn't been working for me.
