The following soft lockup occurs when fstests' ext4/303 test is executed with
64k block size on a ppc64 machine running linux-4.8 kernel.

Thanks for report! I had a look into the code and I'm not sure why this
happens. Is this reproducible? Did it happen also with older kernels?

Yes, This issue can be recreated every single time the test is executed. The
bug is present atleast from linux-v4.0 version. I haven't verified if the bug
is present in earlier versions of the kernel.
