There is currently a data-corruption bug in the RAID-6 md layer (raid6main.c). I have so far not been successful in locating it, although it is easily reproducible, thanks to a set of scripts by Jim Paris. I suspect it is a race condition between raid6d and the rest of the kernel. The problem is that I already have way too many projects in flight, and I *really* would like to focus the time I have on getting klibc/early userspace integrated. Thus, I don't expect to have any time at chasing the RAID-6 corruption bug any time soon. What can be ruled out is errors in the RAID-6 algorithm codes, however. Those are easily testable in isolation and have a clean bill of health. -hpa
