Hi Jens, Ted, and Andreas, A co-worker of mine found a 100% reproducible oops that happens when a IOMEGA USB 3.0 hard drive is plugged into a particular machine. It looks like an oops in the block or EXT4 layer, and it doesn't seem to be in the xHCI (USB 3.0 host controller) driver. (Although looking at the log again, it seems show a cut-off oops at the beginning of the log...) This appears on the 3.0.4 stable kernel. dmesg is attached. Let me know if you need any other info to help solve this issue. Sarah Sharp
