Just to make sure few things:
1. are you really going to setup serial console only guest? because I
saw that nographic and console=ttyS0
2. and the initrd, is that the correct initrd that is built against your kernel?

just a guess: maybe it didn't freeze...it just display things but
toward serial console.... for a test, I suggest (untested) to dump out
-nographic and instead use buit in qemu serial console. Switch to it
by pressing Ctrl-Alt-3 and see if there are message showing there...
