Guys, I can confirm that this issue indeed happens up to the latest kernel (v3.1-rc10-oneiric).
On my usage scenario, I was running a heavy java process for about 20 minutes and the kernel crashed at the same kernel code as above. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/836070 Title: kernel BUG at /build/buildd/linux-3.0.0/fs/buffer.c:3234!
