Hi, Following up my earlier email, I upgraded to 2.6.9-rc1-mm1 and enabled a few of the reiser4 debug options. I did the same command (copy 6G of files from a reiser3 partition to a clean reiser4 partition), and it oopsed again at just under 5G (4999264 1k blocks) - this seems to be a pattern. I got more info in the message log too:
