IANAKH (kernel hacker), but I believe that has to do with detection of really big drives (>137GB) a la Maxtor's "Big drive" initiative. I'd check to make sure your drive is running in the DMA mode that you want, make sure you have an 80 conductor IDE cable, and if all is well I would venture to guess that FreeBSD is sending a query to the drive asking if it uses the 48-bit addressing scheme that Maxtor invented, and the drive has no clue WTF the IDE driver is talking about so doesn't respond, then the ATA driver resets the bus to be safe (after a non-response to a query). This is all speculation, mind you. If everything works, probably nothing to be worried about. >Hi, I get the following message when I boot: > >ad0: 28629MB <WDC WD300AB-60BVA0> [58168/16/63] at ata0-master UDMA100 >(null): MODE_SENSE_BIG command timeout - resetting >ata1: resetting devices .. done > >After the first line is displayed, there is a delay and then the other two >follow.
