Bug#612220: after update to squeeze grub2 don't load the system

[grub2 don't load system: kernel panic]

Package: grub
Version: 0.97-64
Severity: grave

I update my debian lenny to squeeze, and the grub2 was installed (i don't run yet script that complete to change grub to grub2) and system don't loading from grub2, only from grub.
I trying to boot a simple kernel too, not only bpo. From old version of grub all kernels booting good. When i disable quite mode i het the next line:

No filesystem could mount root, tried:
kernel panic - not syncing VFS unable to mount root fs on unknown-block(0,0)
Pid:0 comm: swapper Not tainted 2.6.32-bpo.6-686 #1

And next wiil be a Call trace. Sory i don't know how to copy it and write it by handes i don't want...
If you didn't that the grub calling the grub2 this bug will be critical. And well i can boot my system.
