The only similar debugging I've done is with NFS/RPC, where the
client was using signed int for handles that the protocol says are
unsigned.  It was easy to see that errors were occurring when
the handles were larger than the largest positive int.

Use single user mode with everything else shut down.  You need
some documentation of the protocol so you can look for specific
packets and generate a list of the steps in mounting a filesystem.
Repeating the test on a working configuration may help pin down
the differences.

If you can pinpoint the version where the problem appears you can
start checking individual patches.  Fedora is probably easier in this
respect since there are frequent updates, so only a small number
of patches to consider for each update.
