Kernel Crash, not able to get a dump so far.

I have had my system lock up a few times. At first it seemed to be fairly spread out. But appears to be happening more frequently.

Fatal trap 12: page fault while in kernel mode

Hardware was running stable prior to reinstalling with 2.4, running on ZFS. Has done it twice today, once during early morning hours before I was awake. and once again this evening. Console is completely unresponsive after crash, only way to reset is hardware power cycle.

Hardware is:
Jetway Intel Celeron N2930 Quad Core
with 4G ram, and 30G mSATA SSD.
