This is the only mismatch I could find in your log.  What I couldn't
find was the matching write to 0x0017c9e4.  Still unable to see the
actual bug.  Hmm.

Can you start out with a fresh image, run your testcase and get a
complete log?  I hope that it contains both a crc mismatch like this
and the write of the node before.

Quite likely the log will be too large for this list.  A link to a
webpage would be sufficient, if that is possible.
