Or is this gp fault happening with that patchset? I hadn't gotten around to applying them to my testing tree. Worth noting that of the dozens of oopses I've seen the last few days I think I only saw this one once. (Though I've narrowed my testing scope right now to try and tickle those fs/namei.c bugs, so it could just be that I'm not exercising the codepaths that caused the ipc bug) Dave
