Since 3.16-rc1 my laptop's just goes black while booting, instead of
switching to native screen resolution and showing me the starting
system there. It's an Acer TravelMate B113 with i915 driver and
acer_wmi. It stays black and is unusable.
Do you have other people complain about that? Bisecting didn't lead to a
good result. I could be wrong but I somehow suspect the mistake to be
somewhere in commit 99678ed73a50d2df8b5f3c801e29e9b7a3e5aa85
There is nothing unusual in the kernel log.
This is quite unusual for an -rc2. Hence my question. I'm happy to test
changes.

In order to confirm if the problem is introduced by the above commit,
why not checkout the kernel just before and after this commit and see if the problem exists?

So maybe I was wrong. d27050641e9bc056446deb0814e7ba1aa7911f5a is still
good and aaeb2554337217dfa4eac2fcc90da7be540b9a73 is the fist bad one.
This is a big v4l merge. I added the linux-media list in cc now.
What could be the problem here?

I'm not sure about that. I have no problem with v3.15 and the screen
goes black way before a display manager is started. It's right after the
kernel loaded and usually the screen is set to native resolution.
Bisect told me aaeb2554337217dfa4eac2fcc90da7be540b9a73 as the first bad
one. Although, checking that out and running it, works good. not sure if
that makes sense.

thanks for checking. This does not change anything though. I tested the
following on top of v3.16-rc2 and linus's tree as of today, almost -rc3.

commit. why is this not revertable exactly? how can I show a complete

It seems that _nobody_ is running a simple 32 bit i915 (acer) laptop.
rc6 is still unusable. Black screen directly after kernel-loading. no
change since rc1.
Seems like I won't be able to use 3.16. I'm happy to test patches and am
happy for any advice what to do, when time permits.

Martin, I am running happily a 32-bit kernel 3.16-rc*all on i915 (Asus
EeePC)
However: from your postings I still have no idea what Intel video
chipset is in your Acer.
Try to add "nomodeset=y" to your kernel's cmdline to verify that it can
boot. You have many kobject messages which are hiding what is
happening... And please submit at least full dmesg output and "lspci
-nn" ;-)

Martin, I know nothing about aaeb25543372 and why it should be relevant,
but if you're having rc1..rc6 32-bit i915 black screens, please try this
patch that Daniel Vetter put in his fixes queue on Monday, which I'm
hoping will reach Linus for -rc7.

[PATCH] drm/i915: fix freeze with blank screen booting highmem
x86_64 boots and displays fine, but booting x86_32 with CONFIG_HIGHMEM
has frozen with a blank screen throughout 3.16-rc on this ThinkPad T420s,
with i915 generation 6 graphics.
Fix 9d0a6fa6c5e6 ("drm/i915: add render state initialization"): kunmap()
takes struct page * argument, not virtual address. Which the compiler
kindly points out, if you use the appropriate u32 *batch, instead of
silencing it with a void *.
Why did bisection lead decisively to nearby 229b0489aa75 ("drm/i915:
add null render states for gen6, gen7 and gen8")? Because the u32
deposited at that virtual address by the previous stub failed the
PageHighMem test, and so caused no harm.

yes! thanks Hugh. On top of linus' current tree, that finally fixes my
problem! I hope it'll be included soon!

I'm glad to hear it, Martin, thanks for letting us know. It is now
commit 88b98287356762cc16c9ff6cd48116160a5d4dba in Linus's tree for rc7.
