Hi Andrew, since 2.6.14-rc4-mm1, my second ata_piix (SATA) controller does not show up in dmesg, effectively hiding /dev/sdb. 2.6.14-rc2-mm2 and older (with the same kernel config) were ok, the same for Linus' kernels: 2.6.14-rc5 without -mm1 has /dev/sdb, too. 0000:00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150 Storage Controller (rev 02) (prog-if 8f [Master SecP SecO PriP PriO]) 0000:00:1f.2 0101: 8086:24d1 (rev 02) This PCI device (on-board on an Asus P4 mainboard) has two SATA connectors, showing up as ata1/sda and ata2/sdb. dmesg from 2.6.14-rc5: libata version 1.12 loaded. ata_piix version 1.04 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 0xEFE0 ctl 0xEFAE bmdma 0xEF60 irq 177 ata2: SATA max UDMA/133 cmd 0xEFA0 ctl 0xEFAA bmdma 0xEF68 irq 177 ata1: dev 0 cfg 49:2f00 82:7c6b 83:7b09 84:4003 85:7c69 86:3a01 87:4003 88:207f ata1: dev 0 ATA, max UDMA/133, 240121728 sectors: ata1: dev 0 configured for UDMA/133 dmesg from 2.6.14-rc5-mm1: libata version 1.12 loaded. ata_piix version 1.04 ACPI: PCI Interrupt 0000:00:1f.2[A] -> GSI 18 (level, low) -> IRQ 193 PCI: Setting latency timer of device 0000:00:1f.2 to 64 ata1: SATA max UDMA/133 cmd 0xEFE0 ctl 0xEFAE bmdma 0xEF60 irq 193 ata1: dev 0 cfg 49:2f00 82:7c6b 83:7b09 84:4003 85:7c69 86:3a01 87:4003 88:207f ata1: dev 0 ATA-7, max UDMA/133, 240121728 sectors: LBA ata1: dev 0 configured for UDMA/133 Need more information? I could try to disable a few patches from your -mm series if you name some.. it's too hard for me to guess which one could be responsible for the breakage.
