That sounds like the system I have, which gives me very little trouble

I did have trouble booting 2.4 kernels until I set the legacy kernal option
(CONFIG_ALPHA_LEGACY_START_ADDRESS=y) because I have an older MILO, but
if you're trying to boot a 2.2 kernel that's not it.

I also set my root device on the command line, because I've built at least
one kernel where the default was wrong.

The contents of two relevant /proc files:
frost:~# cat /proc/cpuinfo

frost:~# cat /proc/cmdline
bootdevice=sda3 bootfile=vmlinuz.experimental root=/dev/sda3

If forget exactly how that looks from a MILO prompt (I don't reboot often),
probably something like "boot sda3:/vmlinuz.experimental root=/dev/sda3".

If that doesn't help, some more details about exactly how it is freezing
and the last messages from the kernel would help in debugging.
