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.

If your official HB build is really based on linux-linaro than there must be some changes from 3.14.53 to 3.14.60 which affects PCI in a bad manner. But I can't find any changes in the patch files that are related to PCI or DTS. The board is able to boot with *60 as long as I don't have any PCI card (e.g. Intel WIFI) in the slot. With a card in the slot it hangs on "waiting for /dev to complete" (I don't know the exact phrase). I hoped that only the FSCL kernel is affected but currently it seems like both kernels have that problem. EDIT: I just found and Issue opened by you, that exactly matches my error using your official HB build (and dev from OpenELEC).

Hey, which kernel did you use for the provided Hummingboard image (wheezy)? Is it a self-patched linux-linaro or the latest from solidrun (linux-fslc)? My test tells me, that it is the one from solidrun as I'm not able to use PCI on my HB pro. I've recognized it using the current devel of OpenELEC which also uses kernel 3.14.60 from solidrun. An older version of OpenELEC (e.g. 6.0.3) or Armbian (eg. 4.4 using 3.14.53) works quite good. The PCI driver and the dts changed quite a lot between those kernel repositories. Do you have any suggestions how to fix that? My tries all ended in a boot hang (black screen).
