I don't need the vmdk, but if there is some other repeatable process that can trigger this for you, getting that will allow me to recreate the issue myself. For example, installing Debian into a vmdk, reboot, and then fsck'ing from inside the vm would trigger it. Finding some sort of repeatable process that can trip the bug but without using any of your specific data would be the best way to move forward with the bug. -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx ry...@us.ibm.com -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
