Bug#779452: Additional Info Bug#779452
Well I have been able to narrow it down a bit.
- It is definitely a 945GM/i915/KMS issue.
- The freeze happens exactly at the moment resolution is changed in the
framebuffer.
- If I boot 10 times with "nomodeset", it is 10 times ok without freeze
(however this leaves me with max 1024x768 on a 1280x800 panel which
isn't practical as a workaround).
- If I add intel_agp and i915 to initramfs (to load them early in the
boot process), the freezes still happen and they happen much earlier
(before LUKS etc) at the point where the framebuffer would change
resolution.
I've noticed there are (old) notes on 945M in the wiki:
https://wiki.debian.org/KernelModesetting#Intel_GfxCards
But I verified and it seems we currently ship with these values built-in
by default, so it doesn't apply here.
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE_ROTATION=y
Please tell me if you want me to do additional testing.
