As indicated in my reply to Pete, I decided to replace the machine after it began exhibiting failures to boot properly after problems with the BIOS occured.

Crash dumps were enabled, but never got written to disk (Swap on ZFS is a bad idea). In any case, there wasn't any disk activity when this problem occured, that's what puzzled me the most.
