Hello, sorry to be a pain, but for some reason I am getting a symoops under 2.5.62, yet everything works fine in 2.5.58 (although i notice reiserfs corruption in that one. not good) The symoops only comes after the raid-5 has finished rebuilding, or if i try to mount it whilst its still in degraded mode/rebuilding. either way, it crashes. md: md0: sync done.
