Works perfectly, but I just noticed one really odd thing: 1. boot without ahci.ko: nas-pmh# atacontrol cap ad4 ... write cache yes yes 2. boot with ahci.ko: nas-pmh# camcontrol identify ada0 ... write cache yes no Well? ;-) The system is a HP NL36 - I just found a couple of articles mentioning that the default setting in the BIOS setup was write cache disabled. I can check that in the next couple of days when I take the machine back to the lab (no monitor/keyboard at my home office). I'd prefer a way to make sure write cache is enabled via some tuning from FreeBSD. The disks are dedicated to a raidz2, so from what I found around the net, write cache should not pose a major problem. Of course, one will lose _some_ data at a power outage - what I want to avoid for home office use is a completely lost file system. Losing the last time machine backup of my Mac is tolerable.
