Yup.
I'm currently debating whether I should just remove the printk (for 3.8) or actually do the iovec truncation by hand. The "remove the printk" is a bit cheesy, but I suspect it's the simpler/safer alternative.
Just for info, can you add a "WARN_ON_ONCE()" to handle_bad_sector() just so that I see which particular path your kvm load triggers.
