x locks up after putting display to sleep and at random instances

[wdesmet]

Binary package hint: xserver-xorg-video-ati

On this laptop I have frequent issues with X hanging up. It hangs in two (possibly not related) ways:
1) When in power management "put display to sleep..." is enabled, letting it go to sleep will frequently make it lock up. Input will not bring the screen back up and the machine no longer responds to pings etc. No particular output is logged in syslog.
2) at seemingly random times the display will corrupt (showing a repeating pattern, for example just a couple green/blue lines repeated over the length of the screen) and the machine becomes unresponsive.

I've not been able to track down the source, though at this point I'm pretty sure it's related to the drivers and not the hardware (have replaced some of it). It happens pretty consistently, at least a couple times a day when intensively using the machine, usually with several apps such as eclipse and firefox open. It's been a problem since at least the previous release.

This is an ati radeon xpress 1100 card in an acer 5102WLMi laptop running on lucid with version 1:6.13.0-1ubuntu5 of the driver.

Is there any way you can attach a copy of /var/log/Xorg.0.log.old immediately after rebooting from one of these crashes? There's nothing in the logs attached here to indicate a problem.

I will do as soon as I reproduce it again. I haven't found a reliable way to trigger it so this might take a while. It seems to me this is an interaction with the DRM code, meaning the kernel locks up completely and logging just stops, so it's possible nothing ever gets written to the log file to give any indication to the problem. Which, I realise, makes this a very hard problem to track down.

It does seem to happen more reliably when the machine is under load. I don't really see it happening when I'm just letting my laptop run, but when I have some remote session open, a few browser windows, my mail etc, it seems to happen a lot more quickly.

Log from after a recent crash (blank screen) attached. Nothing in there that I can tell.
