My machine is/was running -mm3 on a software raid1 setup.
After the upgrade to -mm4 it boots to the point where it says:

md: Autodetecting RAID arrays.
md: autorun ...
md: ... autorun DONE.
md: Loading md_d0: /dev/sda
md: bind<sda>
md: bind<sdb>
raid1: raid set md_d0 active with 2 out of 2 mirrors
md_d0: p1 p2 p3 < p5 p6 p7 p8 p9 >
CacheFS: filesystem mounted read-only

LOOK HERE ^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^
VFS: Cannot open root device "md_d0p1" or unknown_block (254,1)
Please append a correct "root=" boot option


Me too, and I boot from a normal ide drive. Disable CacheFS and
you will boot.

In my case, the block was (33,1), drive was hde1.
It looks like cachefs is doing something strange....

I swear, I just disabled CacheFS and the same kernel booted.

Hope this helps.
