OK, I can reproduce that on the Vaio, thanks.

oops: http://userweb.kernel.org/~akpm/dsc00037.jpg
config: (what you sent)
dmesg: http://userweb.kernel.org/~akpm/dmesg-sony.txt

An inspired guess led me to suspect the driver tree. The offending patch
is gregkh-driver-kset-convert-block_subsys-to-use-kset_create.patch.

There's some kobject warning which comes out when
gregkh-driver-kset-convert-block_subsys-to-use-kset_create.patch isn't
applied. More bisecting coming up..
