dmesg

Description of problem:
After logging in to X, and starting an application (firefox, terminal), or sometimes even at the login screen everything on the desktop freezes (even the mouse cursor animation). I can still move the mouse, but nothing responds, and switching terminals with ctrl+f1, or killing X with ctrl+alt+backspace doesn't work either.

It doesn't seem to matter what I am doing, after being logged in to X for a short while it freezes.

Version-Release number of selected component (if applicable):
I used this LiveCD (booted from a USB disk):
http://jlaska.fedorapeople.org/live/livecd-fedora-testday-nouveau-20090325-x86_64.iso

How reproducible:
Always

Steps to Reproduce:
1. Boot Fedora LiveCD
2. Login to X
3. start an application (firefox, terminal). After about 2 minutes X freezes.
  
Actual results:
X freezes, unusable, killable only via kill -9

Expected results:
X usable, applications working

Additional info:
Since X was unusable, before logging in I switched to a VT, opened a ssh tunnel to my laptop.
Now I was able to kill X when it freezed (via kill -9). The desktop's image was still there though, even after I executed (chvt 5).
So I blindly logged in as liveuser, and typed startx. Few minutes after using X it froze again.

I was watching dmesg and I noticed that right after freezing I get this message:
[drm] PFIFO_DMA_PUSHER - Ch 1

I also noticed this message (earlier):
[drm] Allocating FIFO number 0
DMA-API: debugging out of memory - disabling
[drm] nouveau_fifo_alloc: initialised FIFO 0

Comment 4 Ben Skeggs 2009-04-17 07:07:41 UTC 
Can you update to libdrm-2.4.6-6.fc11 and xorg-x11-drv-nouveau-0.0.12-29.20090417gitfa2f111.fc11 and retry?

Thanks.

With the above 2 packages downloaded from koji.fedoraproject.org, and using the Fedora 11 snapshot 1 LiveCD, nouveau works!
I can login, run firefox, play video, etc. without freezing/crashing.
Nice job! You can close this bug.

The only problem I encountered is that totem playback fullscreen toggling causes slowdowns: https://bugzilla.redhat.com/show_bug.cgi?id=496213

Note that using the versions on the Fedora 11 snapshot1 LiveCD, the display freezes even before the login dialog is shown.
