Hi all, I have same problem, booting with 2.6.12-1.1372_FC3smp on Dell SC1425 with SATA /dev/sda yields: ata_piix: Unknown symbol ata_port_start insmod: error inserting '/lib/ata_piix.ko': -1 Unknown symbol in module and loader subsequently oopses after it fails to mount root. modprobe.conf does indeed contain: alias scsi_hostadapter ata_piix No issues booting from the stock FC3 kernel: SCSI subsystem initialized libata version 1.02 loaded. ata_piix version 1.02 ACPI: PCI interrupt 0000:00:1f.2[A] -> GSI 18 (level, low) -> IRQ 177 PCI: Setting latency timer of device 0000:00:1f.2 to 64 ata1: SATA max UDMA/133 cmd 0xCCF8 ctl 0xCCF2 bmdma 0xCCC0 irq 177 ata2: SATA max UDMA/133 cmd 0xCCE0 ctl 0xCCDA bmdma 0xCCC8 irq 177 ata1: dev 0 cfg 49:2f00 82:346b 83:7f01 84:4003 85:3469 86:3c01 87:4003 88:207f ata1: dev 0 ATA, max UDMA/133, 78125000 sectors: lba48 ata1: dev 0 configured for UDMA/133 scsi0 : ata_piix ata2: SATA port has no device. scsi1 : ata_piix Vendor: ATA Model: ST340014AS Rev: 8.12 Type: Direct-Access ANSI SCSI revision: 05 SCSI device sda: 78125000 512-byte hdwr sectors (40000 MB) SCSI device sda: drive cache: write back I'd be happy to use the old kernel if there was a way to revert the kernel-dependent stuff installed by yum (hald, irqbalance), any ideas? == Rich (PS apologies for previous broken message)
