This doesn't look like the same problem. Here we've got BUG: scheduling
while atomic. If it was the bug fixed by the above commits, then you
would hit a BUG_ON. I would start looking at the btrfs bits to see if
they're holding any locks in this code path.
Ignore that one and move to IMG_0350.IMG. 'scheduling while atomic' is
just noise. Besides Mike and Vivek told me to blame you for not pushing
Jens harder on these fixes. :-)))))
