Bug 252793 – Exiting KDE causes lock, loss of video output with 2.6.28-gentoo on x86_64 system.

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Bob Raitz 2008-12-28 10:47:34 UTC]

When operating with the 2.6.28-gentoo kernel, upon leaving KDE, the system locks up. It will not respond to ssh, but will respond to ping. the magic SysRq button will force a reboot. This also happens with 2.6.28 vanilla. 

Reproducible: Always

Steps to Reproduce:
1. use 2.6.28-gentoo kernel
2. Exit KDE normally
3. System locks as described above.

Actual Results:  
System locks with either 2.6.28-gentoo or vanilla sources.

Expected Results:  
Expected normal operation.

Vanilla 2.6.28 .config (for comparison)

Thanks for the report.

@kde team: I think this should be assigned to you. Please feel free to re-assign if appropriate.

what kde version? tried with multiple video drivers? vga or vesa instead of intel? It would really be nice to have more info to go on. I have 2.6.28 working fine with kde4 and both radeon and nvidia-drivers

KDE-3.5.10, No, only the Intel. And I'm actually pretty sure it's a problem with the transition to GEM. I'll set up the (gag) vesa driver for verification, but I'm betting it's a GEM issue.

[Comment 6 Bob Raitz 2008-12-30 06:18:32 UTC]

Testing with the vesa driver shows that this problem is definitely related to the Intel video driver, and how it's interacting. Even when the system was made unstable with microcode enabled (bug #252798), the display didn't lock coming out of X with the vesa driver. 

[Comment 7 Dan Coats 2008-12-30 16:27:50 UTC]

tried rebuilding glibc with the 2.6.28 linux-headers?

How is that going to fix what is OBVIOUSLY a kernel issue? 

[Comment 9 Dan Coats 2008-12-31 14:35:27 UTC]

Looks like a intel driver issue to me... even you yourself said "Testing with the vesa driver shows that this problem is definitely related to the Intel video driver"

Yes, it's either the i915 module(s), or the new drm setup (for intel and GEM), or a deadly combo of both. It doesn't affect my new laptop. However, it seems that this bug pops up with my old Toshiba laptop. I'm not going to run the .28 kernels until the Madagascar Hissing Cockroaches are gone.

@X11:

Any thoughts about this?

[Comment 12 Jeroen Roovers (RETIRED) 2009-01-05 17:27:08 UTC]

Which version of x11-base/xorg-server are we dealing with, here? Looks like bug #253718 may be a duplicate with some more details.

@everyone: Please stop posting speculative remarks without providing information about xorg-server/kernel/KDE versions.

xorg-server-1.5.3
KDE-3.5.10
And, I would say it's only like the other bug if the other bug is caused by the presence of 2.6.28.

[Comment 14 Rémi Cardona (RETIRED) 2009-05-07 07:01:06 UTC]

Could anyone try to reproduce this bug on the latest ~amd64 gentoo-sources kernel along with xf86-video-intel 2.6.3 or, better yet, 2.7.0 ?

Thanks

[Comment 15 Theo Chatzimichos (RETIRED) 2009-05-29 19:52:57 UTC]

This isn't a kde related issue so i'll remove kde from CC list

[Comment 16 Rémi Cardona (RETIRED) 2009-05-31 09:09:33 UTC]

Please get back to us.

Thanks
