I would love to see it fixed in the kernel. But hell, I can't even consistently reproduce it now. The test drive I was just working with that was producing the problem has now stopped producing the problem. Go figure. And I actually used a hammer to "simulate" a failing drive problem on that drive (I don't have a large collection of failing drives). Yes, I said a hammer, always thinking creatively :) But if there is anything I can do to help report the problem, then please let me know.

Maybe we need an entirely different approach - namely we need to post
this as a potential bug in the linux kernel?

Sure. The difficult part is preparing a test case so that the kernel developers can reproduce the problem. ;-)


Best regards,
