Wheezy installer problems

[Martin Smith <martin@rakupottery.org.uk>]

I downloaded today an AMD64 wheezy CD1, a couple of problems:
It locks up on detect network hardware, and if I try an expert install 
and avoid the network bit it gets as far as starting up the partitioner 
40% and stops again.

It is 
http://cdimage.debian.org/cdimage/wheezy_di_beta1/amd64/iso-cd/debian-wheezy-DI-b1-amd64-CD-1.iso

On a Sony Vaio VGN-SR41M which actually runs squeeze, very nicely, but 
on another drive.

Are there any workarounds for this errant behaviour? Or do I have to 
wait for a fix?

cheers
