I've been experiencing the same problem as well. I discovered that the disk on which the filesystem was had some bad sectors causing dump -0Lauf to fail while taking snapshot causing the system to panic. Running smartctl on the device indicated that there were bad sectors 40% within the surface scan being performed by SMART. The drive, an 80 GB Maxtor, was replaced with a 250 GB Western Digital (for a very good price, so good a price I purchased two of them). It was 906 days old, having only been powered off maybe a dozen times over the last three years.
