Hi, After upgrading rawhide kernel from 2.6.17-1.2608 to 2.6.17-1.2614 my SATA hard disk is not recognized anymore. The motherboard is a ASUS P5B with an Intel ICH8 controler and a JMicron JMB363. The only way to get the drive recognized by the kernel (2608) is setting the BIOS SATA configuration in IDE mode (instead of AHCI). Here is an extract of dmesg working with kernel 2608: [...] ata1: SATA link down (SStatus 0 SControl 300) scsi1 : ahci PM: Adding info for No Bus:host1 ata2: SATA link down (SStatus 0 SControl 300) ata_piix 0000:00:1f.2: version 2.00 ata_piix 0000:00:1f.2: MAP [ P0 -- P1 -- ] ACPI: PCI Interrupt 0000:00:1f.2[B] -> GSI 19 (level, low) -> IRQ 177 PCI: Setting latency timer of device 0000:00:1f.2 to 64 ata3: SATA max UDMA/133 cmd 0xEC00 ctl 0xE882 bmdma 0xE400 irq 177 ata4: SATA max UDMA/133 cmd 0xE800 ctl 0xE482 bmdma 0xE408 irq 177 scsi2 : ata_piix PM: Adding info for No Bus:host2 ATA: abnormal status 0x7F on port 0xEC07 scsi3 : ata_piix PM: Adding info for No Bus:host3 ATA: abnormal status 0x7F on port 0xE807 ata_piix 0000:00:1f.5: MAP [ P0 -- P1 -- ] ACPI: PCI Interrupt 0000:00:1f.5[B] -> GSI 19 (level, low) -> IRQ 177 PCI: Setting latency timer of device 0000:00:1f.5 to 64 ata5: SATA max UDMA/133 cmd 0xD400 ctl 0xD082 bmdma 0xC880 irq 177 ata6: SATA max UDMA/133 cmd 0xD000 ctl 0xCC02 bmdma 0xC888 irq 177 scsi4 : ata_piix PM: Adding info for No Bus:host4 ata5.00: ATA-7, max UDMA/133, 234441648 sectors: LBA48 ata5.00: ata5: dev 0 multi count 16 ata5.00: configured for UDMA/133 scsi5 : ata_piix PM: Adding info for No Bus:host5 ATA: abnormal status 0x7F on port 0xD007 PM: Adding info for No Bus:target4:0:0 Vendor: ATA Model: WDC WD1200JS-00M Rev: 02.0 Type: Direct-Access ANSI SCSI revision: 05 PM: Adding info for scsi:4:0:0:0 SCSI device sda: 234441648 512-byte hdwr sectors (120034 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: drive cache: write back SCSI device sda: 234441648 512-byte hdwr sectors (120034 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: drive cache: write back sda: sda1 [...] Salu2 -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
