Interesting, might be a config issue then.

We're using the following fragments with this kernel:
http://git.linaro.org/gitweb?p=kernel/configs.git;a=blob;f=linaro/configs/linaro-base.conf;h=c2f23b19f3c5887399d884c162ef0a8cb40ebc15;hb=refs/heads/config-core-3.4

Final config http://paste.ubuntu.com/1061884/

Will give it a try with ubuntu-minimal.conf.

Also happens when using the ubuntu-minimal.conf fragment.

Final config with ubuntu-minimal.conf: http://paste.ubuntu.com/1062075/

Guess it's probably coming from linaro-base.conf, as ubuntu-minimal.conf is quite minimal :-)
