i see the intel i915 black screen issue is back

[Robert P. J. Day]

  just built a new kernel for ubuntu 10.10 (2.6.38-rc2) and,
depressingly, this kernel once again boots to a black screen given the
intel i915 onboard video.  this is getting frustrating.

Then let the i915 developers know about this, they just fixed a number
of issues relevant to this.

Complaining on a random mailing list will not get this resolved, no
matter how much we wish it were so :)

thanks,

Just pulled and tried on my two i915 machines, and I cannot reproduce
this (Arch Linux). Boot works as expected.

  point taken.  that was just some residual frustration left over from
weeks of tolerating that problem, to see it *finally* (or so i
thought) go away, then to suddenly come back right when i'm trying to
put together a LUG talk on building a new kernel.  grrrrrr.

  so the obvious question is, is anyone else seeing this problem back
again?  i note one person who claims that things still seem to work.
anyone else?  or could it really just be something weird i've done?

p.s.  i posted to the dri-devel list, let's see what i hear back.

There have been a lot of changes recently to this driver, so regressions
are expected, expecially in the middle of the development cycle.

Please report them to the developers and work with them to resolve them,
that's the best way.

good luck,

  in case anyone is interested, i regressed to 2.6.38-rc1 and that
works fine.  and "git log" shows me that there were a number of
i915-related commits after that.

  if i get some time later, i'll do a bisection.

It worked on my Ubuntu-Desktop. Ubuntu version: 10.4.
Please see the attached config file (I have not enabled/disabled any
config parameter - it is a default one).

  oh, we've been having an exciting time on the dri-devel list with
this.  if anyone wants to play along, the current workaround is to
take the git-bisected bad commit (b705120e), and deactivate a chunk of
functionality:

$ git diff
diff --git a/drivers/gpu/drm/i915/intel_opregion.c b/drivers/gpu/drm/i915/intel_opregi
index 64fd644..27f677e 100644
--- a/drivers/gpu/drm/i915/intel_opregion.c
+++ b/drivers/gpu/drm/i915/intel_opregion.c
@@ -470,6 +470,8 @@ int intel_opregion_setup(struct drm_device *dev)
        u32 asls, mboxes;
        int err = 0;

+       return -ENOTSUPP;
+
        pci_read_config_dword(dev->pdev, PCI_ASLS, &asls);
        DRM_DEBUG_DRIVER("graphic opregion physical addr: 0x%x\n", asls);
        if (asls == 0) {


  at this point, the job is to narrow down where in that file the
problem is occurring.  it's clear that others are not seeing this so
i can only imagine it's some combination of my hardware and its
version or something.
