[RV350] system freeze randomly unless XAA used

[MyName]

Binary package hint: xorg

Hi,

I did a clean Jaunty install. Now I have the problem that the System freeze randomly. I cant't reproduce the freeze. It happens randomly 1-2 times a day at browsing with firefox, searching with Gnome-Do or nautilus or at idling.

The Keyboard and mouse stop working too. REISUB doesn't work, have to push Powerbutton to power-off system.

Intrepid works fine, there was no problem with freezes.

Hi rapha,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

Hi,

I have the same GPU as yours, also a clean install of Jaunty and the same problems. It occurs in three types of freezes:
 - the mouse moves, everything else is unresponsive (sometimes REISUB helps)
 - a black screen
 - something completely different, might be my laptop - the screen fades into a blue/violet color with strange patterns (I could try and take a photo if this ever happens again (it happened twice))

None of this happened in Intrepid. Moreover, the system becomes stable after disabling Desktop Effects (I'm using KDE4), but then some screen corruption shows up occasionally.

I've attached my lspci -vvnn.

[Antanas Uršulis (antanas-ursulis-deactivatedaccount)]

Ok, disregard what I said about the system becoming stable, it still freezes from time to time (but really less often than with desktop effects). I've attached my Xorg.0.log from a recent freeze.

[Paul Weiss (interweiss)]

I have the same problem with Ubuntu 9.04 AMD64. I have a Nvidia video card if that makes a difference.

[Paul Weiss (interweiss)]

After upgrading to Firefox 3.0.10, I don't get these freezes any more.

[MyName (rk.)]

I think this is a ati driver issue, not firefox.

have firefox 3.0.10 and the system is still freezing

[MyName (rk.)]

Hi,
I updated the driver to "xserver-xorg-video-ati - 1:6.12.2-0ubuntu1~xup~1 " (and the other packages) with one of the Ubuntu-X-Swat PPA

The System is still freezing.

******

For testing I installed Intrepid Ibex Ubuntu parallel to Ubuntu Jaunty, this installation is running fine, NO freezes.

[Mantas Zimnickas (sirex)]

Same problem here. When I was using Gnome + Compiz freezes where more frequent, now I'm using LXDE without Compiz, but once a week my laptop still freezes.

Also, here is logs, when I first time restarted after freeze.

[Tormod Volden (tormodvolden)]

Since your card is an AGP Radeon card, this might be an AGPMode issue. Please see https://wiki.ubuntu.com/X/Quirks#ATI%20AGP%20Mode%20Quirk and report back.

You other guys with other cards, please file your own bugs.

[Mantas Zimnickas (sirex)]

I found, that my problem was related to Ext4 and not with video drivers. When my computer starts to write into lots of small files, computer just freezes.

[MyName (rk.)]

@Tormod Volden

I switched three days before to Karmic, 3 days no freezes yet. If a freeze occur, I try the workaround with AGPMode.

[MyName (rk.)]

I turned on Compiz and the System is freezing after a few minutes. Tried the workaround setting AGPmode to 1 / 2 / 4, doesn't help.

@Raphael

Is your system running fine now? And could you perhaps post the contents of your xorg.conf ?

I've got the same video card, running Kubuntu jaunty with latest updates and experience these freezes all the time. Even when idle, the Xorg uses 20-50% of cpu time. And all of this without running compositing.

I can also confirm that this didn't happen with Intrepid. Everything ran smoothly _with_ compositing.

[MyName (rk.)]

No freezes since I switched from EXA to XAA. Compiz is running smoothly to.

[Gobnuts (gobnuts)]

Thanks Raphael

It's weird. I tried a modified xorg.conf with just the "AccelMethod" "XAA" and that ran as crappily as before (20-50% cpu time for X).

I decided trying to re-install vanilla Jaunty (quite radical solution, but I figured I might have some crap installed I didn't remember and wanted to exclude that).

The only alteration to xorg I have right now is: Driver "radeon"
I can live without compositing, but it still bugs the hell out of me, what the high cpu usage of X was.

Here's hoping that someday compositing on R300/R350 chipsets will work again sometime, I know it did under intrepid.

[Bryce Harrington (bryce)]

Raphael, I stuck in a patch to -ati today which forces XAA in some circumstances, but I'm uncertain if it is going to do it for your case. Would you mind retesting today's -ati update in Karmic and see if it solves the issue even if you do not specify XAA in your xorg.conf?

[MyName (rk.)]

I tested it without Option "AccelMethod" "XAA". The System freezes after 1-2 minutes.

Please attach the new log.

[Tormod Volden (tormodvolden)]

OK, the new version also defaults to EXA. It will only force XAA if you are low on VRAM, but your 64MB is considered enough.

Many random freezes issues have been fixed in Karmic or xorg-edgers, so if you have the possibility of trying them out it could be worthwhile.

[Gytis Raciukaitis (noxxious)]

This is still happening in karmic with the driver from the KMS ppa, no matter that even XAA is specified (although I suspect it still uses EXA).
The only option to avoid is to to have EXA and EXANoComposite turned on, but then this makes everything horribly slow.

Gytis and Gobnuts, since you have slightly different cards or issues, it is better that you file your own bugs.

[Gytis Raciukaitis (noxxious)]

Tormod,

although I'm running karmic now, this bug was seen by me on Jaunty as well. Whenever EXA is enabled the hard freeze is happening. This is still experience in karmic regardless of KMS.

I have played around with the options a bit:
| DRI | RenderAccel | Freeze |
+++++++++++++++++++++++
| yes | yes | yes |
| no | yes | yes |
| no | no | no |
+++++++++++++++++++++++

The freeze usually happens after some time and mostly with firefox & flash. For example browsing for some time with Chromium and then launching firefox can cause a freeze.

[Problem]
X freezes after about 1-2 minutes unless XAA used. The system has 64MB so XAA is not getting forced on by default.

This is a regression from Intrepid to Jaunty, verified as still affecting Karmic, and tested against git up to commit f39cafc5 via xorg-edgers, and by another user with the same hardware up to commit 20090805.bd03977e.

hi,

following the recommendations on the other defect on freedesktop I have force the card into the PCI mode using the radeon driver option radeon.agpmode=-1 in karmic.

After that I'm running with no problems for one week. I guess this should work with non KMS setup as well.

[Rolf Leggewie (r0lf)]

sounds a lot like bug 363238

[Gytis Raciukaitis (noxxious)]

No, this is a different issue. In this case EXA is actually performing, but causes system hard freeze.

[Mrsteven (mrsteven)]

Same here with all radeon driver releases that support render accelleration with EXA (latest I've tested is xf86-video-ati-6.12.4). The system freezes completely, even the music stops to play.

My current setup on gentoo:
x11-base/xorg-server-1.6.3.901-r2
x11-drivers/xf86-video-ati
media-libs/mesa-7.5.1

When I switch to AccelMethod "exa" it works fine again, but with EXA the system freezes, usually when I'm scrolling a website in firefox.

I have also been affected by this bug since Ubuntu Jaunty (just found this bug last night). I was disappointed to find that the hard freezing still occurs under Karmic. Freezing happens within a few minutes with compiz running; it happens in a matter of days without compiz running (usually when moving a window, alt-tabbing, or opening a menu). Metacity with composite running and AccelMethod set to XAA seems to be doing fine so far.

I would like to do whatever I can to help get this fixed.

Michel, please let me know what to try. Would you like every combination of the options you posted tested? I am also available on FreeNode as 'chromakode' if you'd have things you'd like me to test.

Thank you,

That seems to do the trick. Haven't tried the other options yet, but with this EXA is stable, even with AIGLX and Compositing from KDE 4. Without the BusType Option the system freezes quite quickly.

Packages are as follows:

$ emerge -pv xf86-video-ati mesa libdrm vanilla-sources xorg-server

Can you try changing the AGPMode? Remove the BusType option and try:
Option "AGPMode" "X"
where X = 1 or 2 or 4 or 8

[Spoek (spoek)]

I may have the same problem here.
If I use XAA, everything works fine but Xorg recommends me to use EXA over XAA.
If I use EXA, the graphical login appears corrupted, specially the fonts. If I log in, the system freezes in a few seconds. Even the SysRq combo doesn't work.

I've tried the next:
With "BusType" "PCI" I get "(WW) RADEON(0): Option "BusType" is not used".
Options "EXANoUploadToScreen" and "EXANoDownloadFromScreen" are useless, the freeze continues.
Option "EXANoComposite" gives me a working system but, in exchange, it seems to make X a very cpu hungry process.

My GPU is an "ATI R300 AD [Radeon 9500 Pro]". I'm on a Gentoo box using the git version of the graphic stack through the x11 overlay.

Please, feel free to ask for more information or if you want me to try a patch.

Can you attach your xorg log and dmesg? It sounds like you may be using KMS, in which case, there is only EXA support as XAA doesn't work with kms.

I'm sorry, I forgot to tell that, indeed, I'm trying to use KMS. As you can see in dmesg, my kernel is from git also: 2.6.33-rc8.

I can attach my .config if you wish but these are the related parameters to radeon in it:
CONFIG_DRM_RADEON=m
CONFIG_DRM_RADEON_KMS=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FB=y
# CONFIG_FB_RADEON is not set

My last build from git was in March 5th but I can catch up if necessary, kernel included.

I've found that drm-radeon-testing commit 924788672f9c802a4c8e6bc8d88fbc2c9b2e3089 ('drm/radeon/bo: add some fallback placements for VRAM only objects.') can result in GPU lockups due to the 3D engine trying to access unbound GTT memory, and the new GPU reset code can hardlock the system when trying to recover from the lockup. If your kernel has that commit, try reverting it.

Note that this report was about non-KMS so your problem should be tracked elsewhere.

My kernel doesn't have that commit :(
I've followed your recommendation and I've filed a new bug report: #27355 (https://bugs.freedesktop.org/show_bug.cgi?id=27355)

I did not have the problem with the kernel 2.6.33 series (that I used for at least 2 months while writing my thesis), KMS and xf86-video-ati-6.13.0. Today I updated to Kernel 2.6.34 and I got the same freeze again. The system runs with radeon.agpmode=-1 right now, let's see if it crashes again.

Anyway, I think in this case it's more of a kernel bug...

[pedro_magalhaes86 (pedro-magalhaes86)]

I believe I have similar problem with my laptop, a LG LW65 Express. I am using Ubuntu 10.04 and it works fine, but sometimes the screen goes black and the system simply doesn't respond, requiring a so called hard reset. My VGA card is an ATI x700 mobility. In my opinion, the crashes are completely random. They don't happen because I start an extremely demanding application, they come out of nowhere.

[Sebastian (sebastianhaselbeck)]

same here. random freezes (mainly when using on battery, but also on cord), with blank screen. seems to be graphics adapter related, or buffer overflow, who knows.... on thinkpad edge 13 with amd/ati combo, 64bit.... please fix :(

[Tormod Volden (tormodvolden)]

Closing bug, no response from original submitter.

Sebastian, your comment sounds like a completely different issue. Please file a new bug using "ubuntu-bug xserver-xorg-video-ati".
