I looked at the code in 2.6.32 and I can't find the related bits in handle_stripe6(). The prexor int isn't defined, and the checks after set_bit(R5_Wantwrite, &dev->flags); aren't issued. I don't know enouch about this code to see what's going on. I'm also not sure what really triggers this bug. I tried setting up a raid6, failed two drives, starting to write a bunch of deterministic data to the drives and started to rebuild it - no errors could be detected, neither in metadata or data.
I have a vm setup with lucid for this purpose, and I can allow access to it for deveopers wanting to test.
