I have a 4.10 system that I'm trying to build a bootable DVD for (for disaster recovery purposes). Whilst it boots OK, it won't mount root from the native ATAPI device but only off the SCSI emulation. Has anyone else seen this? The ISO image is built with mkisofs -b boot/cdboot -no-emul-boot -r -J -V MY_RELENG_4_10 -o foo.iso /home/root The relevant parts of the dmesg are: atapci0: <VIA 8233 ATA133 controller> port 0xfc00-0xfc0f at device 17.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 ... acd0: DVD-R <SONY DVD RW DRU-700A> at ata1-master UDMA33 cd0 at ata1 bus 0 target 0 lun 0 cd0: <SONY DVD RW DRU-700A VY03> Removable CD-ROM SCSI-0 device cd0: 33.000MB/s transfers cd0: cd present [2295104 x 2048 byte records] All the following root specifications failed with ENXIO: cd9660:/dev/acd0c cd9660:acd0 cd9660:acd0c but cd9660:cd0c worked. -- Peter Jeremy
