    • Resolved uninitialized node access.
    • fixed a bug that caused echotest failure when NPIV is enabled.
    • fcauthd 1.19 is now required for fibre channel authentication.
  • dm-multipath now has inbox support for IBM DS4000.

  • the iwlwifi drivers have been updated to version from 2.6.26, adding 802.11n support to iwl4965 wireless devices. Several bug fixes included in post-2.6.26 versions of the driver were also incorporated into the backported driver.
  • the myri10ge driver for Myricom Myri-10G Ethernet devices has been updated to version 1.3.2-1.269.
  • the netxen driver for NetXen network cards has been updated to version 3.4.18.

Storage
  • 3w-xxxx: driver for 3ware SATA RAID Controllers updated to version 1.26.03. This applies several upstream changes, most notably:
    • Fixed a bug that caused data corruption when using a 3ware 7000 or 8000 series card in a system with greater than 2GB of RAM.
    • Anaconda no longer hangs on 64-bit architectures when using a 3ware 8006 series card in a system with greater than 4GB of RAM.
    • The irq handler is now freed when __tw_shutdown() is initiated. This prevents a possible null pointer de-reference if an interrupt was shared during shutdown.
    • RCD bit for caching mode page is now turned on.
    • ioctl resets and scsi resets are now serialized so they no longer collide.
  • 3w-9xxx: driver for 3ware SATA RAID Controllers updated to version 2.26.08. This applies several upstream changes, most notably:
