I don't know whether this one is relevant or not but it is in fs/namei.c and it could mean vfs regression. I got the oops below after resuming from disk today, kernel is 38-rc5. However, it didn't happen yesterday on resume so it either is a glitch or a bug which is hard to reproduce. I'll run -rc6 to check. Beware, I've typed the whole oops from the screen, and while I paid attention and made sure I had enough coffee before starting, some typos might've sneaked in. I doublechecked the "Code:" section though. -- [19728.090341] ------------[ cut here ]------------ [19728.090511] kernel BUG at fs/namei.c:1416!
