Also, it would be nice to get this into libata-dev or -mm to get some more exposure.. I tested it on a NF4-Professional system with 8GB RAM and a single SATA disk. It first did nicely in LTP and some other tests, but during a bonnie++ run it eventually blocked with all IO hanging forever. No output either. I did a full backtrace and it just showed the processes waiting for a IO wakeup. -Andi sata_nv 0000:00:07.0: Using ADMA mode PCI: Setting latency timer of device 0000:00:07.0 to 64 ata1: SATA max UDMA/133 cmd 0xFFFFC2000003C480 ctl 0xFFFFC2000003C4A0 bmdma 0x1C10 irq 22 ata2: SATA max UDMA/133 cmd 0xFFFFC2000003C580 ctl 0xFFFFC2000003C5A0 bmdma 0x1C18 irq 22 scsi0 : sata_nv ata1: SATA link down (SStatus 0 SControl 300) scsi1 : sata_nv ata2: SATA link down (SStatus 0 SControl 300) ACPI: PCI Interrupt Link [LSI1] enabled at IRQ 21 ACPI: PCI Interrupt 0000:00:08.0[A] -> Link [LSI1] -> GSI 21 (level, high) -> IRQ 21 sata_nv 0000:00:08.0: Using ADMA mode PCI: Setting latency timer of device 0000:00:08.0 to 64 ata3: SATA max UDMA/133 cmd 0xFFFFC2000003E480 ctl 0xFFFFC2000003E4A0 bmdma 0x1C20 irq 21 ata4: SATA max UDMA/133 cmd 0xFFFFC2000003E580 ctl 0xFFFFC2000003E5A0 bmdma 0x1C28 irq 21 scsi2 : sata_nv ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata3.00: ATA-6, max UDMA/133, 312581808 sectors: LBA48 ata3.00: ata3: dev 0 multi count 16 ata3.00: configured for UDMA/133 scsi3 : sata_nv ata4: SATA link down (SStatus 0 SControl 300) scsi 2:0:0:0: Direct-Access ATA ST3160023AS 3.18 PQ: 0 ANSI: 5 ata3: bounce limit 0xFFFFFFFFFFFFFFFF, segment boundary 0xFFFFFFFF, hw segs 61 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
