Subject: kernel BUG at fs/buffer.c:3205

Hi,

there is currently a thread "kernel BUG at fs/buffer.c:3205 (stable 3.5.3)" on this list.

I have reached the same BUG_ON(), but in an older kernel and with a different environment, so maybe the following information is helpfull.

- Kernel is from openSUSE 12.2: kernel-desktop-3.4.6-2.10.1.x86_64
- I have no SSD and no USB 3.0
- The BUG occured when updating DVD ISOs with jigdo on an ext4 partition (old and new ISOs are on the same partition).
- No fglrx module, but unfortunately a nvidia module
