Cannot boot after update to Maverick

After updating to Maverick from Lucid, the kernel (linux-image-2.6.35-22-generic) seems to be unable to boot. The old one (linux-image-2.6.32-24-generic) boots flawlessy. I have both at this moment on grub2.

Steps to reproduce this error:

Install Lucid with /dev/sda1 as reiserfs;
Upgrade to Maverick;
Boot with "2.6.35-22-generic".

After reboot you'll get the messge "Kernel Panic: VFS: Unable to mount root".

Also I've got a (poor) picture with my cellphone camera (if needed, please ask a copy).
