I don't know what happened between last night and tonight (besides a cvsup and a new kernel), but I didn't have a panic, and my nightly dump completed DUMP: DUMP: 2832388 tape blocks on 1 volume DUMP: finished in 931 seconds, throughput 3042 KBytes/sec DUMP: level 0 dump on Wed Apr 16 05:30:28 2003 DUMP: Closing /dev/da0s1 DUMP: DUMP IS DONE As you can see, it only took about 15 minutes with USB 2.0, as opposed to well over an hour to complete the dump with USB 1.0.
