Bug#1029968: Info received (Bug#1029968: Acknowledgement (bttv/v4l: WARNING: CPU: 6 PID: 6164 at mm/vmalloc.c:487 __vmap_pages_range_noflush+0x3e0/0x4d0))
Note that the oops at this bisect point is messier than on the newer
kernels; the newer kernels hit a WARN in __vmap_pages_range_noflush, where
as at this point it slams into a BUG, but the rest of the backtrace is similar;
