>Description:
When using the ahci driver instead of the ata driver, my drive times out on an Asmedia 1061 controller.

ahcich0: Timeout on slot 0 port 0
ahcich0: is 00000000 cs 00000001 ss 00000000 rs 00000001 tfd 451 serr 00000000 cmd 0004c017

ahcich0: AHCI reset: device ready after 100ms                                   


>From a kernel with the ahci driver disabled, here is the pci information for the card:

atapci0 at pci0:13:0:0:	class=0x010601 card=0x10601b21 chip=0x06121b21 rev=0x01 hdr=0x00
>How-To-Repeat:
Boot a system with an asmedia 1061 controller and the ahci driver enabled.
>Fix:
This setup has been running fine for over a year using the ata driver instead of ahci.
