>Description:
FreeBSD-CURRENT (at least amd64) does not see SATA drive on ASUS A8N-SLI MB (nForce4 chipset). Thus it does not boot here (this is the only HD). Tested with both my custom and GENERIC configurations for 2 last days - boot stops rith "cannot monutroot". HW: Athlon64, ASUS A8N SLI (not Deluxe), 
ad0: 152627MB <Seagate ST3160827AS 3.42> at ata4-master SATA150
>How-To-Repeat:
