You are hitting this:
BUG_ON(bitmap_allocate_region(vb->dirty_map, offset >> PAGE_SHIFT,
order));
Which indicates this is most likely a bug in the vmalloc code, not a bug in the
XFS code. I'd reassign the bug to the VM component, but it looks like I can
only reassign it to another filesystem (stupid!). So, you'd probably do best to
report the 2.6.37 version of this problem to linux-mm@xxxxxxxxx and
linux-kernel@xxxxxxxxxxxxxxx with a pointer to this bugzilla...
Cheers,
Dave.
