I have 2 computer with 2 different Asrock (http://www.asrock.com/product/775Dual-880Pro.htm) boards, both have a VIA8237 and a VIA SATA, and both are quirked wrongly, when I use kernels 2.6.17+ . And if I haven't bought this 2 computers in a supermarket, I won't be here discussion this subjects.
So I like to remember http://lkml.org/lkml/2006/7/28/264 http://lkml.org/lkml/2006/9/4/111 ( that confirm a VIA SATA on XT-PIC mode ) http://lkml.org/lkml/2006/9/1/106 )
So VIA SATA needs my patch or Daniel Drake patch to _WORK_ .
Adding my patch to Daniel Drake patch ( that is already on -mm series ) could be a reasonable solution.
Patch for 2.6.18-rc5-mm1
