Hi Chris, i have been retesting some thing as i could not see any difference with https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1107642/comments/22
so after digging into my test stick i saw that that post was with testing the kernels on raring instead of quantal. So i have done some digging as why i got loading driver null and it seems that my initrd was built without plymouth/framebuffer. Starting the quantal system with an initrd made from raring (only changing the root parameter) everything worked as expected. So now i have retested the kernel https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1107642/comments/34 and it boots correctly without issues. This only works when building the initrd with FRAMEBUFFER=y in /etc/initramfs-tools/conf.d/splash Sorry for my mistake, but it seems that adding 9a0f938bde7 to a default quantal kernel fixes the crash regarding i915 ppgtt.
