More oops with reiser4 on x86_64

2004-08-29 Thread Hamish Rodda
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.

- 2.6.9-rc1-mm1 has a bug that affects all filesystems (pointed out earlier today). so don't use if you love your data ;) Can you tell us more about this bug? (I'm using 2.6.9-rc1-mm1 and would like to know, what will happen ;) ) See: http://marc.theaimsgroup.com/?l=linux-kernel&m=109360433916523&
