Hi, This bug still exists in 3.1.0 and 3.2.0-rc5 I spoted it again few days ago, because I moved from me laptop with 2GB to temporary desktop with 256MB of RAM, and not it triggers like a mad. So my initial suspicious that it only shows up on big memory presure was correct. It is just like this # dmesg | grep dirty [122647.953872] JBD: Spotted dirty metadata buffer (dev = dm-3, blocknr = 1019852). There's a risk of filesystem corruption in case of system crash.
