That 8890029 seems wrong (see below).

The math in the disklabel doesn't seem to work:
  1837 * 4811 = 8837807

which is not 8890029.  Also, rsd2e is going to try to write to block
(8428156+461087) 8889243, which is also not within 8837807..

I'd guess you're falling off the end of the drive...

Hope this helps...
