Sometimes when I select a piece of text in firefox and begin dragging it, the X server locks up. It has time to change the cursor though, and cursor updates continue to work so it isn't completely hung. There are no other updates on the screen except for the cursor though. This is extremely annoying as the only way to recover is a hard reboot. Just pressing the power button isn't working (probably as g-p-m is popping up its dialog on the unusable display). My card is a NVS 140M (G8x) in a Thinkpad R61.
Can you upload your /var/log/Xorg.0.log.old and /var/log/messages from after you've done a hard reboot after the hang.

Hmm, I'm not seeing anything from the GPU to indicate the driver did anything wrong. Just to confirm it's a problem with the graphics driver, are you able to switch to the nv or vesa driver and see if you can repeat this with them?
I tried nv and I'm unable to provoke it there.
this only happens with nouveau; with nv, and the proprietary driver, it doesn't happen.
Today the X server crashed instead of locking up. Nothing in the Xorg log unfortunately, and only these lines in messages: Apr 20 08:47:28 mjolnir kernel: nouveau 0000:01:00.0: Pushbuf config exceeds limits: Apr 20 08:47:28 mjolnir kernel: nouveau 0000:01:00.0: dwords : 17447 max 16381 Apr 20 08:47:28 mjolnir kernel: nouveau 0000:01:00.0: buffers: 2 max 1024 Apr 20 08:47:28 mjolnir kernel: nouveau 0000:01:00.0: relocs : 4 max 1024 Apr 20 08:47:28 mjolnir kernel: nouveau 0000:01:00.0: nouveau_fifo_free: freeing fifo 2 Apr 20 08:47:29 mjolnir kernel: nouveau 0000:01:00.0: Allocating FIFO number 2 Apr 20 08:47:29 mjolnir kernel: nouveau 0000:01:00.0: nouveau_fifo_alloc: initialised FIFO 2 Since the original report, I've switched to KMS. Perhaps that's why it managed to restart X instead of simply locking up.
Wow, I've never seen that trigger before :) I had a very quick look, one one thing's immediately coming to mind that could cause this to happen, can you try the build at http://koji.fedoraproject.org/scratch/bskeggs/task_1308928/ and see if it helps any?
No difference. Same noise in dmesg: nouveau 0000:01:00.0: Pushbuf config exceeds limits: nouveau 0000:01:00.0: dwords : 45904 max 16381 nouveau 0000:01:00.0: buffers: 2 max 1024 nouveau 0000:01:00.0: relocs : 4 max 1024 nouveau 0000:01:00.0: nouveau_fifo_free: freeing fifo 2
I managed to reproduce it here with a new user, guess my normal theme manages to not trigger this somehow. Should be fixed as of xorg-x11-drv-nouveau-0.0.12-30.20090421git47bb00f.fc11 (http://koji.fedoraproject.org/koji/taskinfo?taskID=1310297). Can you confirm it works for you?
Seems so. Good work. :)
Cool, that's good enough for me! Closing :) Thanks for testing!
