I'm playing with a custom file system on this, so it could be related. I haven't made any modifications to any kernel code directly, or any UFS code, but I did have my custom file system mounted at the time. I'll let it run for a while if anyone has any ideas to try. No dump device set up, but I do have serial access and such.
