X hanging | radeon:radeon_read_ring_rptr: NULL pointer dereference at (null)

[Odin Hørthe Omdal]

Just hitting away in VIM in gnome-terminal, and on changing tab the whole computer froze. Was able to SSH into it, and everything seemed pretty normal.

Killed X and then these errors came:

Actually, this time we lost the picture, and dmesg says this:

Is there any workaround?

[Jeremy Foshee (jeremyfoshee)]

Hi Odin,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 496566

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I want to give that machine away, so I shall try to test it this
evening with Lucid. It sadly lacks internet now though, so it's a bit
hard to do it. But I'll see what I can do (maybe carry it to my office
;-) ).

Yes, it's still an issue on lucid as of now. As a workaround I use fbdev, like this
$ sudo ln -s /etc/X11/xorg.conf.failsafe /etc/X11/xorg.conf
