Description Frank Seidel 2009-03-16 09:49:50 UTC

As soon as dri is enabled and i switch to text console _and_ back the system freezes (black screen and no keyboard actions are taken (no ctrl-alt-del, no ctrl-alt-backspace)).
Could be related to this bug?

As a consequence this of course breaks any suspend (to disk and to ram).

Comment 4 Frank Seidel 2009-03-16 10:08:32 UTC

Stefan has the same problem on a msi wind with intel gfx.

Comment 5 Marcus Meissner 2009-03-16 11:08:21 UTC

I see the same with lenovo x61

Comment 6 Frank Seidel 2009-03-16 17:20:18 UTC

I think this could be related:

Comment 7 Stefan Dirsch 2009-03-16 17:56:54 UTC

Would be easy to figure this, Simply install kernel from openSUSE 11.1/SLE11.

Comment 8 Frank Seidel 2009-03-16 18:22:23 UTC

No, at least on my system reverting the mentioned commit didn't change anything. So its probably not related.

Comment 9 Stefan Dirsch 2009-03-16 19:11:27 UTC

So it's not related to

  http://bugzilla.kernel.org/show_bug.cgi?id=12765

The issue there is described a regression in 2.6.29 since 2.6.28. Kernel is 2.6.27 on 11.1/SLE11 and 2.6.29 on STABLE/Factory.

Comment 10 Stefan Dirsch 2009-03-17 03:55:54 UTC

Oops. You only reverted the commit, so it could still be related to STABLE kernel.
Please give 11.1 kernel a try. Thanks.

Comment 11 Frank Seidel 2009-03-17 08:20:09 UTC

Yes, it seems to be related to the stable kernel: after installing and booting the 11.1 kernel the problem was gone.

Comment 12 Forgotten User ZhJd0F0L3x 2009-03-19 15:59:02 UTC

It also works with the FACTORY kernel-of-the-day
2.6.29-rc8-master_20090318143000_93ad0879-default
Source Timestamp: 2009-03-18 15:30:00 +0100

so closing as fixed
