Ok, bk4 works for you and bk8 doesn't. So try the following:
- test bk6
- if bk6 fails test bk5
- if bk5 fails, the problem happened between bk4 and bk5
- if bk5 works, the problem happened bewtwen bk5 and bk6
- if bk6 works test bk7
- if bk7 fails, the problem happened between bk6 and bk7
- if bk7 works, the problem happened between bk7 and bk8

And let us know what the result is, please.
