Your system is trying to tell you something :-) Well of course the bad block is h/w. But deleting a raid0 on a hard error is insane. I can more-or-less understand for raid1 why that might be thought sensible, but a split raid0 is of no use for anything. Nor could I find anywhere in the kernel that actually deletes the raid. But for sure -stable from 9/24 behaved differently (ie, sanely) on getting the error than -stable from 10/13 or so. I don't think that's hardware.
