I've been dealing with Mike Frysinger on the linux-mtd list and he
recommended that I shoot this up to you guys.
His comment was "your config though says you only have 1 block starting
at 0x60000 with a length of 0x20000.  so there's no reason it should be
testing 0x80000 -- after all, you only care about bytes 0x60000 -
0x7ffff."


I am hoping there is something that I am doing that is causing this.  I
would appreciate some info.

Thank you.
