i search in google and i get thesame problem, though he solved his. here it is: From: glenn@antimatter.net (glenn@antimatter.net) Message 1 in thread Subject: ad0: READ command timeout Newsgroups: sol.lists.freebsd.stable View this article only Date: 2002-11-26 02:04:03 PST I just put together a new system using a Shuttle SS51G with a P4 2.53GHz, 512MB RAM, and a 80GB Maxtor UATA133 HD (DiamondMax Plus 9). Booting from the 4.7 install CD the system would hang with the following message: ad0: READ command timeout tag=0 serv=0 - resetting ata0: resetting devices .. I manually set hw.ata.ata_dma=0 and was able to boot and install 4.7. I cvsuped to the latest -STABLE but booting with hw.ata.ata_dma=1 still hangs the system with the same message. Disabling UDMA in the BIOS will also allow the system to boot. I searched the mailing list archives, but couldn't find anything that looked relevant (other than setting hw.ata.ata_dma=0). Any help would be greatly appreciated. If I need to provide more info, just let me know what to provide. Below is dmesg output (with a GENERIC kernel) and uname -a output. (the dates are wrong as I had not yet set the clock) -Glenn HE MANUALLY SET : hw.ata.ata_dma=0 any ideas how to do that too? hope for your reply guys __________________________________________________ Do you Yahoo!?
