[Arm-dev] Kernel problems on APM X-Gene

Hey everyone!

I cannot get any kernel past 4.5.0-23.el7.aarch64 to work on APM X-Gene hardware. This includes the new (CentOS 7.4) 4.11.0-22 kernel.

The last thing ever displayed during boot is this:

EFI stub: Booting Linux Kernel... EFI stub: Using DTB from configuration table EFI stub: Exiting boot services and installing virtual address map... L3c Cache: 8MB

which is usual. However, nothing is logged to /var/log/messages (presumably it isn't making it far enough in the boot process) and I'm not sure how to further troubleshoot the issue.

Has anyone else been successful? Are there new patches I am unaware of? Can someone please help me debug deeper?

Thanks in advance!
