To the general mailing list: I would like to request additional help to resolve the sata issue on imx6. I have done a preliminary reading of the CAM code and have looked at the change made to the ahci driver late last year for arm support. I have inspected the dts files. I have done some poking a while back into what is loaded and not loaded. However, I do not know how to properly debug a CAM driver (or any kernel level code) or use the debug tools. My personal objective is to become a FreeBSD driver maintainer, and I have been tracking this issue for a while, but I have stalled out at this point. I need a higher level of support then the mailing list provides to become productive (at least initially). At this point learning how to debug kernel devices by myself is outside of my scope. However, if someone is willing to Skype or chat/email with more directed support I will pick this project back up. I would love to earn a commit bit eventually. Please send me a message if you can help. Cheers, Russ > > On Thu, 2016-02-18 at 11:57 -0800, Russell Haley wrote: > > My hummingboard booted two days ago using r294912.
