Nope, dd doesn't cause a crash anymore (rebooted and ran a full memtest86+ pass); although it does segfault if I attempt to dd /bin/cat into /dev/null or /dev/zero.
I believe some earlier conditions may have caused an inconsistent state in the kernel which got triggered by the dd attempts; however, I do not see why dd should segfault. There may be a bug in dd; or the kernel may be doing something that ties into these BUG reports. Unfortunately this is as far as I can go with this; I have no method to reproduce it, hopefully some kernel guru figures this out. The only lead I have is that you should check to make sure 'dd' doesn't have a bug itself. 'cat /bin/cat > /dev/null' doesn't segfault so I doubt there is a specific kernel bug; but we'll see. The above messages have to come from somewhere. -- kernel bug, you figure it out. https://launchpad.net/bugs/57642 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
