      HP Compaq nc6000 suffers from the double disk spindown issue.
      Add it to the broken poweroff DMI list.

      ahci: add warning messages for hp laptops with broken suspend · 9b10ae86
      Tejun Heo authored
      
      
      Harddisks on HP dv[4-6] and HDX18 fail to come online after resume on
      earlier BIOSen.  Fortunately, HP recently released BIOS updates for
      all machines to fix the issue.  Detect old BIOSen, warn the user to
      update BIOS on boot and suspend attempts and fail suspend.
      
      Kudos to all the bug reporters.

      pata_efar: fix PIO2 underclocking · 5f33b3bc
      Sergei Shtylyov authored
      
      
      Fix the PIO mode 2 using mode 0 timings -- this driver should enable the
      fast timing bank starting with PIO2, just like the PIIX/ICH drivers do.
      Also, fix/rephrase some comments while at it.

      pata_legacy: wait for async probing · 45bc955b
      James Bottomley authored
      
      
      The basic problem here that pata_legacy attaches the host, sees if it found
      any devices and detaches it if none were found.  With async probing, it's not
      waiting until discovery is finished before deciding it has no devices and
      trying the detach leading to this warning:

      Because it detaches before the probe is complete.
      
      One way to fix it would be to put an async_synchronize_full() before looking
      for devices, which this patch does.  A better way might be to separate libata
      into its own domain and only wait for that.
