Date: Mon, 26 Mar 2007 14:32:18 -0300 From: Matías Alejandro Torres <torresmat@...il.com> To: linux-kernel@...r.kernel.org Subject: SB600 and SATA disk in 2.6.21-rc5 Ubuntu 6.10 with kernel version 2.6.21-rc5 compiled with ahci support I have a MSI K9AGM motherboard that ships with four SB600 SATA ports but when the kernel is booting it shows some errors and the SATA disk is not detected. Here is what dmesg throws: dmesg: [ 1.332000] ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx [ 1.332000] ahci 0000:00:12.0: version 2.1 [ 1.332000] ACPI: PCI Interrupt 0000:00:12.0[A] -> GSI 22 (level, low) -> IRQ 16 [ 2.336000] ahci 0000:00:12.0: AHCI 0001.0100 32 slots 4 ports 3 Gbps 0xf impl SATA mode [ 2.336000] ahci 0000:00:12.0: flags: 64bit ncq ilck pm led clo pmp pio slum part [ 2.336000] ata1: SATA max UDMA/133 cmd 0xf8824d00 ctl 0x00000000 bmdma 0x00000000 irq 222 [ 2.336000] ata2: SATA max UDMA/133 cmd 0xf8824d80 ctl 0x00000000 bmdma 0x00000000 irq 222 [ 2.336000] ata3: SATA max UDMA/133 cmd 0xf8824e00 ctl 0x00000000 bmdma 0x00000000 irq 222 [ 2.336000] ata4: SATA max UDMA/133 cmd 0xf8824e80 ctl 0x00000000 bmdma 0x00000000 irq 222 [ 2.336000] scsi0 : ahci [ 2.648000] ata1: SATA link down (SStatus 0 SControl 300) [ 2.648000] scsi1 : ahci [ 3.132000] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 33.132000] ata2.00: qc timeout (cmd 0xec) [ 33.132000] ata2.00: failed to IDENTIFY (I/O error, err_mask=0x104) [ 34.112000] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 64.112000] ata2.00: qc timeout (cmd 0xec) [ 64.112000] ata2.00: failed to IDENTIFY (I/O error, err_mask=0x104) [ 64.112000] ata2.00: limiting speed to UDMA7:PIO5 [ 65.092000] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 95.092000] ata2.00: qc timeout (cmd 0xec) [ 95.092000] ata2.00: failed to IDENTIFY (I/O error, err_mask=0x104) [ 96.072000] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 96.072000] scsi2 : ahci [ 96.384000] ata3: SATA link down (SStatus 0 SControl 300) [ 96.384000] scsi3 : ahci [ 96.696000] ata4: SATA link down (SStatus 0 SControl 300) ############################## lspci -vvv: 00:12.0 SATA controller: ATI Technologies Inc SB600 Non-Raid-5 SATA (prog-if 01 [AHCI 1.0]) Subsystem: Micro-Star International Co., Ltd.
