Boot screenshot showing white boxes
This is my first bug report up here, please bare with me.
I get these white boxes (see screenshot) when booting from an initramfs generated by Dracut 008 on Gentoo. Dracut upstream suspect a problem outside dracut. While I normally do use a Gentoo-modified kernel, vanilla Linux 2.6.38 shows the same behavior.
Is there anything I can do?
Bug persists with 184.108.40.206. Happens without Dracut, too.
My active graphics card is the Intel one of these:
# sudo lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3400 Series
Excuse me, I am re-opening because:
- The problem persist in recent kernels.
- No explanation was given why the bug is invalid.
If you close as invalid again, please help me understand why. Thanks!
Because nothing had happened since 2011 and because it appeared to be to do with the userspace. Just having a general prune of old bugs - not particularly picking on yours
Now it's re-opened and known current hopefully it'll shake a branch or two.
Do you only see the white rectangles during dracut or do they appear in X or console too ?

Alan, I think you picked the wrong component.
Indeed - moved. And that would make more sense as there is another 'squares' report. in i915 space.
Wonder if someone isn't always clearing up sprites and overlays ?

Great to see some action.

Only at the first few console lines flying by long. Happens with dracut and/or genkernel. No issues in X.
Is this still an issue on latest kernels? Tbh it looks like something in fbcon doesn't properly draw stuff - the other white box bug looks quite a bit different.

> Is this still an issue on latest kernels?
Yes, the issue persists with Linux 3.6.6.
Worth retesting with 3.8-rc kernels - the takeover sequence from the BIOS config is markedly different, and we've fixed a few "dirt in framebuffer" issues.

> Worth retesting with 3.8-rc kernels
Just tried 3.8-rc3, the very latest by the time of your last reply.
The bug persists with 3.8-rc3. I can give 3.8-rc4 a spin too, if you wish.
Please re-open, the requested info has been provided.
Very similar to bug 17121.
Could you re-open this bug? It's still marked NEEDINFO despite all info being provided by now. Thanks!
Is this fixed in 3.9, specifically by

drm/i915: Clear the stolen fb before enabling

Sadly not, issue persist with 3.9.0.
It seems nobody has any ideas. I can only ask if the issue is still present in 3.12?

Running vanilla 3.12.5 now, issue persists :(
No real ideas, but
1) Please provide a dmesg of the boot, with drm.debug=0xe module parameter.
2) Please boot without i915 or i915 blacklisted with modprobe.blacklist=i915

Output of "dmesg | fgrep drm" from Linux 3.12.5

It's from Linux 3.12.5. I applied filter "fgrep drm" to mitigate potential privacy issues. If that's an issue, I could send the unfiltered log to you directly or something.
Sounds like something that Jesse's fb takeover patch might fix. If not then it's the hilarious fail called vgacon->fbcon takeover, which is unlikely to ever get fixed (because *shudder*).

Without i915 it doesn't switch to higher resolution and seems to hang somewhere before disk encryption wants my password. With i915 back in, boot goes well as usual. Now speaking of 3.13.2.
How do we proceed?
Can we turn NEEDINFO back to ASSIGNED? Do you need something more?
I think it'd be good if you can test Jesse's latest patches a bit. There's still a few missing pieces which aren't yet merged ...
Jesse can you please proved a branch somewhere?
Latest bits are in the inherit-bios branch of git://people.freedesktop.org/~jbarnes/linux.

Presents to me as 3.13.0+, same white boxes during start-up.
Jesse' patches have been merged to drm-intel-nightly for 3.15. Presumably fixed by those, please reopen if that's not the case.

Just tried drm-intel-nightly (commit 8f5284d0165252f41609a97acc2755234b22cf15): still showing white boxes. Re-opening.
Can you please retest with 3.15-rc? That has the fb takeover patches from Jesse (finally!) and might actually help this time around.

Running 3.15.0 by now: still showing white blocks.
Please revert from needinfo to re-opened (and from P3 to P1 if it was for my delay in replying).

We defaulted all non-regressions to P3.
Sadly, I can only ask you to try a recent kernel. We may have fixed the bug, but we're quite obviously clueless about any of our fixes having a connection to this particular bug.
If I can trust my eyes the white blocks are gone in 3.16.2.

I'll quickly close this one before you have more doubts about your eyes. Fingers crossed. Thanks for bearing with us.
:) Many thanks for the fix!
