This hint was very helpful. After regenerating all initrds with 
"update-initramfs -u -k all" none of the kernels worked 
(same problem as 3.2.6). 

I then manually downgraded initramfs-tools to 0.98.8 (stable) and created all
initrds again and now it worked even with 3.2.6.

So it seems to me, that this is rather a bug of initramfs-tools (0.101).
I'll try to figure out the differences between the two initrds.

Thanks,

Johannes
