Bug#853170: fails to boot on debian's MP30-AR1 systems [regression]

2017-01-30 Thread Peter Palfrader 
Package: linux-image-4.9.0-1-arm64
Version: 4.9.6-3
Severity: grave
User: debian-ad...@lists.debian.org
Usertags: needed-by-DSA-Team

The 4.9.6-3 kernel package fails to boot on Debian's aagaard and acker
systems.  4.9.2-2 before that booted just fine.

This is from the serial:

Bug#853170: fails to boot on debian's MP30-AR1 systems [regression]

2017-01-31 Thread Riku Voipio 
Quick test with 
4.9.2-2 with new arm64 kernel config: boots
4.9.6-3 work old arm64 kernel config: booms

This hints that numerous kernel config changes we did are probably
not the reason, but some of the kernel changes between 4.9.2 and 4.9.6.

Especially between 4.9.5 and 4.9.6 a bulk of arm64 changes went in. So
next logical step is try with 4.9.5 - if that fails, there is only a 
few potential commits for breakage between 4.9.2 - 4.9.5 - and if succeeds
we have a more tedious way to go.
