Re: [PATCH][INCOMPLETE] sata_nv: merge ADMA support

[Matt Heler <lkml@lpbproductions.com>]

Hey Bill,

I spoke abit to soon though regarding that stability.. After booting up X and 
running Azerues and kde, my system stalled and locked. However it lasted much 
longer then Jeff's version. 

I'm running the DFI Lanparty with an Athlon 4400. I also have the following 
setup

2x300gb seagate drives 7200.8 in a raid0 format with ext3
2x400gb seagate drives 7200.9 again in a raid0 format with ext3

and lspci gives me the following :: 

00:06.0 IDE interface: nVidia Corporation CK804 IDE (rev a2)
00:07.0 IDE interface: nVidia Corporation CK804 Serial ATA Controller (rev a3)
00:08.0 IDE interface: nVidia Corporation CK804 Serial ATA Controller (rev a3)
