Public bug reported:

I installed linaro-vivid-alip-20150914-710 as rootfs on a iMX6 board, but Xserver crash at startup.
The behaviour is the same for both 2:1.17.1-0ubuntu3 and 2:1.17.1-0ubuntu3.1 versions.

Installing the debugging symbols I identified a NULL pointer in a strncmp call checking for pci devices (gdb log attached).
Most likely no one experienced such a problem because there are a few armhf boards provide pcie support...

Trying to identify the cause, I natively compiled the server following
the instruction available in build log
https://launchpad.net/ubuntu/+source/xorg-
server/2:1.17.1-0ubuntu3/+build/7089347/+files/buildlog_ubuntu-vivid-
armhf.xorg-server_2%3A1.17.1-0ubuntu3_BUILDING.txt.gz

However the problem is not reproducible building sources natively on
target.

Any suggestion?
