After upgrading my 6-CURRENT box to 2004.11.14.16.00.00 (and also 2004.11.16.19.15.00), I have encountered this crash twice in 24 hours. A system built from sources dated 2004.11.07.07.00.00 stayed up a week straight without a hitch. The system is a dual AthlonMP system. The dmesg from the last boot is attached at the bottom (ACPI disabled). The first crash came with ACPI enabled, the second with it disabled. I do have a dump from the first crash in case someone needs further info.
