Stephan, this one definitely looks strange. Have you tried running other diagnostic tools on you SD card, e.g. fsck? How about on your hard disks or other mass storage devices? Is it always the same block that's reported as bad? Were you doing any suspend/hibernation during these tests? It might also be an idea to turn on CONFIG_DEBUG_PAGEALLOC and run badblocks again. If you turn off CONFIG_HOTPLUG and CONFIG_HIBERNATION on a recent kernel does it work then? I'm pretty stumped as to what is going on here...
