In the FC6 2.6.20 kernels, the IDE driver does not claim the drive; later on ata_piix gets control: Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ide0: I/O resource 0x1F0-0x1F7 not free. ide0: ports already in use, skipping probe In 2.6.22, IDE does: Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx Probing IDE interface ide0... Clocksource tsc unstable (delta = -101028827 ns) hda: Hitachi HTS721010G9SA00, ATA DISK drive So what changed? The configuration looks the same, with IDE built in and the ata driver as a module. -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
