I did not investigate on this issue too much, but there is an workaround - 
copy older /boot/loader over newer one. In my case, I am rebuilding whole
world often, and now /boot/loader seems to not build correctly for me. Older 
one is ~ 250 kB, rebuilt will be ~ 185 kB, and freezes.

In your case, you would write old /boot/loader from 6.3 over new installed 
with 6.4RC1 and it will boot normally again.

I know it is only workaround, but it's quick and easy, and I have not too much 
time to investigate any further (not to mention I have no idea what to look 
for and where).
