To reiterate, I have /boot on USB thumb drive, and the system is mounted from / on a raidz pool called /storage via loader.conf. The four drives in question (per the packaging) are: - Western Digital Caviar SE16 500GB - 7200, 16MB, SATA-300, OEM Per the packaging on the rest of the hardware: # mobo - XFX 610i, 7050 GeForce (I *never* use graphics on my FreeBSD boxen, I *only* know/have CLI with no 'windows') # memory - 2 GB Corsair XMS2 Twin2X 6400C4 memory # cpu - Intel Pentium DC E2200 2.20GHz OEM - 2.20 GHz, 1MB Cache, 800MHz FSB, Allendale, Dual Core, OEM, Socket 775, Processor # swap - I don't run any, but can/will add in an IDE/ATA 7200 200GB in the event this problem may be related to ZFS/RAM issues.
