The precise cause of this is presently not publicly known but seems likely to be a chipset bug. Similar to ServerWorks “frodo”: Hardware does not support hotplug.
NCQ support added in later chipsets nForce4 and later.
Linux Kernel Driver DataBase: CONFIG_SATA_VITESSE: VITESSE VSC / INTEL SATA support
In an effort to provide positive reinforcement, I also make an effort to give priority to performing engineering tasks on open hardware. Has per-device hardware queues, and supports legacy TCQ. These will be supported by the Marvell libata driver in progress, see above. There appear to be some error handling issues in the nForce4 SATA controllers, where system lockups or machine check exceptions can occur when the driver attempts to access the controller registers as part of error handling.
Hardware, driver status From ata Wiki. Users may wish to use the Promise driver to fully utilize the hardware. The SX4 hardware is not fully utilized by the Linux kernel driver.
Intel® 31244 PCI-X to Serial ATA Controller
Looks like a standard AHCI controller, but with a few differences requiring a different driver. I make an effort to highlight vendors that support their chipsets by posting hardware documentation publicly open hardware.
Note that 88 SE xxxx series of chips present an ahci interface. Feature will never be implemented. This has also been known to happen in Windows so it sat not appear to be a driver issue. Usually due to lack of hardware support for features, such as NCQ. Not suited to libata architecture, a separate block driver “sx8” has been written for this hardware.
This support is now enabled by default.
Information on the capabilites of the devices themselves is present in the list of hardware features. The hardware can support this feature, but driver code does not yet exist to support it.
This is not yet supported in Linux.

It generally works quite well but there are some known bandwidth limitations which show up with the higher bandwidth requirements from PMP.

This is now not enabled by default due to some reported issues, such as with hotplug and with command timeouts on some systems. Docs are public yay! Retrieved from ” https: Advanced queueing controller, with full SATA phy control. No, feature is not present. Contents 1 Intsl updates inte, Hardware support 2. Using the on-board DIMM as cache, and issuing each RAID transaction once instead of once for each diskwill result in increased performance, but the driver doesn’t do that yet.
