assuming you have the correct initramfs for your kernel with correct driver
for raid, you may try to pass "debug=y" to the kernel command line. initramfs
should pick it up and maybe output some interesting information before it
panics. most notably what device it tries to use for /root/.
otherwise you'll have to go through initramfs-tools scripts
(/usr/share/initramfs-tools) and add this info yourself, regenerate initrafs
and try again.
One problem I had once upon a time is, that for some reason initrafs couldn't
detect my root filesystem, so I had to add "rootfstype=ext3" to the kernel
command line.
mk
