Both SATA HDD and SATA DVD-RW are connected to Intel ICH7 SATA300 controller. Worked w/o problems using old ata(4) driver, still works OK using ata(4) in ATA_CAM mode. However, loading ahci(4) results in HDD still working, but DVD-RW doesn't even get detected during the boot (I've tried different SATA ports on this controller and different SATA cables - results are the same). Kernel configuration: http://sites.google.com/site/lynxripe/freebsd/pr/20101216-ahci/lynx?attredirects=0&d=1 loader.conf for ata(4) case (for using ahci(4) I simply load it from the loader's prompt): http://sites.google.com/site/lynxripe/freebsd/pr/20101216-ahci/loader.conf?attredirects=0&d=1 Verbose dmesg w/o ahci module (DVD-RW attached by ata(4) and works OK): http://sites.google.com/site/lynxripe/freebsd/pr/20101216-ahci/dmesg-v.boot?attredirects=0&d=1 Verbose dmesg with ahci module (DVD-RW does not attach): http://sites.google.com/site/lynxripe/freebsd/pr/20101216-ahci/dmesg-v-ahci.boot?attredirects=0&d=1 I'm ready to provide any additional information about this HW and try patches on it. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
