I bought a SiI3112-based SATA adapter (Adaptec 1210SA) and a 120Gb drive for my computer a while ago. Unfortunately, I can't get them to work in any sensible manner at the moment. I'm running 2.4.22-pre6-ac1, so by all accounts the chip should be recognised (it is), and put into some form of DMA mode (it isn't) on boot up. Any attempts to access the disk appear to work, but take a _very_ long time, and cause lots of lost interrupts. The relevant sections from the logs when the machine starts up look like this: Adaptec AAR-1210SA: IDE controller at PCI slot 00:0b.0 PCI: Found IRQ 10 for device 00:0b.0 Adaptec AAR-1210SA: chipset revision 2 Adaptec AAR-1210SA: not 100% native mode: will probe irqs later ide0: MMIO-DMA , BIOS settings: hda:pio, hdb:pio ide1: MMIO-DMA , BIOS settings: hdc:pio, hdd:pio ALI15X3: IDE controller at PCI slot 00:0f.0 ALI15X3: chipset revision 193 ALI15X3: not 100% native mode: will probe irqs later ide2: BM-DMA at 0x9000-0x9007, BIOS settings: hde:DMA, hdf:pio ide3: BM-DMA at 0x9008-0x900f, BIOS settings: hdg:pio, hdh:pio hda: ST3120026AS, ATA DISK drive hdc: no response (status = 0xfe) hde: Maxtor 90648D3, ATA DISK drive blk: queue c0340238, I/O limit 4095Mb (mask 0xffffffff) hdg: Pioneer DVD-ROM ATAPIModel DVD-120S, ATAPI CD/DVD-ROM drive ide0 at 0xd4816080-0xd4816087,0xd481608a on irq 10 ide2 at 0x1f0-0x1f7,0x3f6 on irq 14 ide3 at 0x170-0x177,0x376 on irq 15 hda: attached ide-disk driver. hda: lost interrupt hda: lost interrupt hda: lost interrupt hda: host protected area => 1 hda: lost interrupt hda: 234441648 sectors (120034 MB) w/8192KiB Cache, CHS=14593/255/63 hda: lost interrupt hda: lost interrupt hde: attached ide-disk driver. hde: host protected area => 1 hde: 12656448 sectors (6480 MB) w/512KiB Cache, CHS=787/255/63, UDMA(33) Partition check: /dev/ide/host0/bus0/target0/lun0:<3>hda: lost interrupt p1 p2 p3 /dev/ide/host2/bus0/target0/lun0: p1 I've tried most, if not all, of the "fixes" that people have suggested on LKML for this chipset (all the hdparm invocations, for example), and haven't managed to change any of the symptoms I mentioned above. Can anyone suggest any way that I can get this [for me] rather expensive and currently useless piece of hardware working under Linux? I know that Andre Hedrick has fixed some things in an unreleased patch, but it's unclear exactly which problems he's fixed, or when the patch is going to be released. Is anyone in a position to say whether my problem is going to be fixed by his changes, or when that patch is going to be released, if ever?
