Been there, done that. Somebody managed to trip a ground leakage circuit
(aardlekschakelaar in dutch) in this building yesterday. After resetting
that switch my alpha came up without a hitch. A whole lot quicker than
with ext2 too.
My guess is that the ext2-reading-code in milo has been stripped of most
of the compatibillity checks: if it looks remotely like ext2, try to read
it. As long as kjournald has commited all of your new kernel to disk and
out of the journal I think milo will be able to boot.
