Thanks for testing. This is very wield, the req->__data_len is wrong. Is this a clean build?
I just downloaded linux-3.3-rc7.tar.bz2 from kernel.org and applied your patches again. The result is the same. Am I the only one experiencing these problems? This is on a fedora 16 system and it is NOT a virtual machine. It only has 3 SSD's and 6 GiB of ram. Below I have added some more information of the system in case it helps.
