The "git bisect start v3.10 v3.9" itself may not include that fixing
commit, however the bisect script will check latest mainline and
linux-next kernels at the end, and this line shows that linux-next at
that day is still bad:

I confirmed that b148a42ba7823e34971cd4e5b05a5c74fa3311ed does contain
the fixing commit c07fe5ae06.

Thanks,
