-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 After removing atapicam from my kernel, so no panics on boot I decided to see it DMA was fixed for my CD/DVD combo drive. I changed the hw.ata.atapi_dma="0" to hw.ata.atapi_dma="1" in my /boot/loader.conf. After a reboot I tried to access my cdrom drive, and got the following error messages, which is very similar to the messages when trying to dma before ATAng: Aug 26 22:09:34 littleguy kernel: acd0: WARNING - READ_CD recovered from missing interrupt Aug 26 22:09:34 littleguy kernel: acd0: WARNING - READ_CD UDMA ICRC error (retrying request) The problem is that before with DMA enabled it would try dma a few times fail, and then fall back to PIO, whcih though annoying still left the drive in a useable condition. Where as now the drive just stays stuck and unusable. - --- dmesg --- Copyright (c) 1992-2003 The FreeBSD Project.
