Apparently this seems to be the source of many troubles with 4.6. Please see the message included below, forwarded from the FreeBSD-Stable list, and thanks to Doug Barton for providing the initial suggestion that Bruce expanded upon: ------------------------ Begin Included Message --------------------- Date: Mon, 17 Jun 2002 21:32:35 -0700 From: "Bruce A. Mah" <bmah@FreeBSD.ORG> Subject: Re: ATA Atapi 4.6 Release If memory serves me right, John Prince wrote: > Thanks.. > and you are right.. This worked? OK. I'll work on an errata entry for this. Here's my understanding, mostly based on dougb's message plus a little experimenting: This problem is that some users are having difficulty reading CD-ROMs on certain ATA CD-ROM drives. This has been seen on the AOpen 48x, 52x, and 56x CD-ROM drives (are there any non-AOpen drives that have this problem?). The error message one sees is: acd0: READ_BIG command timeout - resetting ata1: resetting devices .. done (In some cases, this is followed by a kernel panic.) We need first-time CD-ROM users (with affected hardware) to interrupt their boot process (at the "Hit [Enter] to boot immediately..." step), and then do: ok set hw.ata.ata_dma="1" ok set hw.ata.atapi_dma="1" ok boot (This gets a working system for a CD-ROM install.) Do the install like normal. After installation is complete, we need to apply the workaround for subsequent reboots. Reboot after finishing the installation and then add these lines to /boot/loader.conf or /boot/loader.conf.local (create as necessary): hw.ata.ata_dma="1" hw.ata.atapi_dma="1" Then reboot one more time. Is that roughly right? I'm mostly interested in getting an errata entry containing the correct workaround out quickly, rather than getting the list of CDROM drives exactly right. We can fine-tune said list later.
