Thanks a million !

I am aware of those problems but have no solution at the moment. Regarding sources - we don't save sources per build - we have Github and history. If you need older version, you need to remove patches which will not help much anyway. You probably mean old 3.14.x kernel sources: https://github.com/linux4kix/linux-linaro-stable-mx6 and new 3.14.x kernel sources: https://github.com/SolidRun/linux-fslc ?
 
My HB v2 is in the air so I expect to get it next week, then I'll start to focus on those problems. I'll go on the route to bring camera and HB v2 support  down to "old" 3.14. kernel, which PCI is working good.

I will try to migrate (maybe tomorrow) the PCI driver from 4.4.x to 3.14.60 (fslc). I've confirmed that PCI is working on that kernel.
 
PCI seems to be broken since a lot of version in fslc, according to threads from the web.
