I found a solution in a thread on this list posted in 2008: It introduces whitelist entries in libata-core.c for devices with well working bridges (e.g. email on Fri, 31 Oct 2008 01:45:27 -0400). I added my device to this whitelist in a custom built kernel and it works fine for weeks now. How can I have this device added on the whitelist within the official kernel? Is this whitelist mechanism still supported or is there a smarter way to achieve whitelisting? I added the following whitelist entry for my Buffalo DriveStation Quattro "BUFFALO HD-QSU2/R5": /* Devices that do not need bridging limits applied */ { "MTRON MSP-SATA*", NULL, ATA_HORKAGE_BRIDGE_OK, }, { "BUFFALO HD-QSU2/R5", NULL, ATA_HORKAGE_BRIDGE_OK, }, Reported-by: Michael Eitelwein <michael@eitelwein.net> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When managing shost->host_eh_scheduled libata assumes that there is a 1:1 shost-to-ata_port relationship. libsas creates a 1:N relationship so it needs to manage host_eh_scheduled cumulatively at the host level. The sched_eh and end_eh port port ops allow libsas to track when domain devices enter/leave the "eh-pending" state under ha->lock (previously named ha->state_lock, but it is no longer just a lock for ha->state changes). Since host_eh_scheduled indicates eh without backing commands pinning the device it can be deallocated at any time. Move the taking of the domain_device reference under the port_lock to guarantee that the ata_port stays around for the duration of eh.

* | | [libata] Add " 2GB ATA Flash Disk"/"ADMA428M" to DMA blacklistPrarit Bhargava2012-05-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A user has several systems with a couple of models of flash disks with IDE connectors. These disks work fine in 2.6.18-ish kernels but corrupt data on new kernels. The difference appears to be with the default I/O method used by the IDE controller driver between the kernels. In the older kernels, the configuration is very conservative and the driver stays in PIO mode. With new kernels, the ata driver (pata_serverworks) attempts to use UDMA/66 which the drive claims to support. This mode, however, does not appear to work in DMA mode. The drive does work correctly and no corruption is seen if the kernel parameter "libata.force=5:pio0,6:pio0" is used to force the driver to use PIO instead of DMA mode. Blacklist these drives. Unfortunately the model name of the drive is very generic, " 2GB ATA Flash Disk", but the revision is specific, "ADMA428M".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ATA and SATA drives have had built-in retries for media errors for as long as they've been commonplace in computers (early 1990s). When libata stumbles across a bad sector, it can waste minutes sitting there doing retry after retry before finally giving up and letting the higher layers deal with it.

In this case we want to use the paravirtualised drivers if we can as they are much more efficient. Note that the Hyper-V paravirtualised drivers only expose the virtual hard disk devices, the CDROM/DVD devices must still be enumerated. Mark the host controller ATA_HOST_IGNORE_ATA to prevent enumeration of disk devices.
