I can reproduce this quite easily, doing:
nelson:~ # splice-cp sda.blktrace.0 foo
nelson:~ # md5sum sda.blktrace.0 foo
4754070ae77091468c830ea23b125d68 sda.blktrace.0
efdc7b9d00692fdfe91a691277209267 foo
'foo' contains only zeroes. Doing the same on ext3 yields the correct
results, foo contains the right data. I'm testing on
2.16.18-rc5-current, Jeffrey used 2.6.17.x latest.
