2.4.32. No - nothing that I know of, but my experience with 2.6.12.3 is
minimal (all kernels later than 2.6.3 tend to lock up my laptop hard - it
may be a graphic card problem).

The trace doesn't go near any enbd code. The get_sb_bdev call is is as
close as it gets, but I don't see any entry into enbd code at all.

You should therefore check (using make test, or the maketest
standalone, on a test file or the raw device with size set greater than
ram) that the enbd device works as it should. 

The only "different" thing about xfs is its 512b (pseudo-)blocksize.
