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.
