I can avoid that in the future while still doing destructive testing, so you don't have to be too reluctant to give me things to test. I just wanted to make sure there was no further utility in getting oopses from Linus's patch. And try_direct_io=0 works just fine, and doesn't seem to have any performance impact or anything, so at this point I'm not losing any sleep.
