Dear Debian Developers, the bug seems still existing on my machine. I'm Using linux-image-2.6.18-4-686 (2.6.18.dfsg.1-11) while the bug report claims to be fixed in 2.6.18.dfsg.1-9. Unfortunately I don't have the time to review the ahci code or the patches made for this bug. But I can support you by testing patches, providing traces etc. The machine used is a Fujitsu/Siemens Esprimo P2510, extract from dmesg output: SCSI subsystem initialized libata version 2.00 loaded. usbcore: registered new driver usbfs usbcore: registered new driver hub ahci 0000:00:12.0: version 2.0 ACPI: PCI Interrupt 0000:00:12.0[A] -> GSI 22 (level, low) -> IRQ 177 ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx 8139cp: 10/100 PCI Ethernet driver v1.2 (Mar 22, 2004) ahci 0000:00:12.0: AHCI 0001.0100 32 slots 4 ports 3 Gbps 0xf impl IDE mode ahci 0000:00:12.0: flags: 64bit ncq ilck pm led clo pmp pio slum part ata1: SATA max UDMA/133 cmd 0xDC81C100 ctl 0x0 bmdma 0x0 irq 177 ata2: SATA max UDMA/133 cmd 0xDC81C180 ctl 0x0 bmdma 0x0 irq 177 ata3: SATA max UDMA/133 cmd 0xDC81C200 ctl 0x0 bmdma 0x0 irq 177 ata4: SATA max UDMA/133 cmd 0xDC81C280 ctl 0x0 bmdma 0x0 irq 177 scsi0 : ahci ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata1.00: ATA-7, max UDMA/133, 156301488 sectors: LBA48 NCQ (depth 31/32) ata1.00: ata1: dev 0 multi count 16 ata1.00: configured for UDMA/133 scsi1 : ahci ata2: softreset failed (1st FIS failed) ata2: softreset failed, retrying in 5 secs ata2: port is slow to respond, please be patient ata2: port failed to respond (30 secs) ata2: COMRESET failed (device not ready) ata2: hardreset failed, retrying in 5 secs ata2: port is slow to respond, please be patient ata2: port failed to respond (30 secs) ata2: COMRESET failed (device not ready) ata2: reset failed, giving up scsi2 : ahci ata3: SATA link down (SStatus 0 SControl 300) scsi3 : ahci ata4: SATA link down (SStatus 0 SControl 300) Vendor: ATA Model: ST3808110AS Rev: 3.AA Type: Direct-Access ANSI SCSI revision: 05 ACPI: PCI Interrupt 0000:00:13.0[A] -> GSI 16 (level, low) -> IRQ 193 Cheers! -- Michael Altmann <ma@aie.de> Altmann Industrieellektronik GmbH
