[Problem]
Karmic Intel GPU hang

[Original Description]
I'm afraid I don't have very much information about this, but I wanted to get a bug report open because it's potentially serious.

I wasn't able to collect any additional information when I observed a hang, because I didn't have access to another system on the same network to ssh in (though based on my observations, I'm confident it was only the GPU. The system responded to sysrq+k, though the console was never properly restored).

If there is another way other than ssh to get a text login on the system when it is in this state, I would like to know so that I can try it if it happens again.



This appeared in syslog around the time of the hang, confirming it's a GPU lockup:

How to reproduce it?

If there's no steady reproduce steps, nor gpu dump, I don't suggest this to be higher priority than other gpu hang bugs.

I'm no longer able to reproduce the problem. It's likely that Eric's mesa patch (about the relocation delta for WM surfaces) mentioned here fixed it:

Good to know this. Let's close it.
