Default Bug#576274: additional info

Hi there,

with some help from one of the maintainers I found the latest package from sid and installed it:
http://packages.debian.org/sid/linux-image-2.6.32-4-686

But the problem remains unchanged. And I still don't have any meaningful log reports. I wanted to add that in former kenel versions (pre 2.6.31) the problem was less frequent, but more severe (e.g. crash also took down x input) . So it might be a different problem.

Also when the screen goes blank it sometimes takes on different shades of grey. From almost white to grey to black. Backlight is on. And when rebooted the screen stays that way until the screen powers all the way down.

With the new kernel version I had an uptime of about 3 hours and only two pm-suspends until the problem occured.

Thanks,

Malte

hmmm,
could you check against 2.6.32-11 should land next days in unstable?

also there is 2.6.33 in experimental, don't think it should make
a difference but better check.

thanks

Default Bug#576274: additional info

I will continue to test new kernels as they come. This has been a long standing issue. In early 2.6.32 kernels I had an error message right after Grub. This went away with later versions. At the same time my own compiled kernels (from recent linux-source-2.6.32) had a blank screen right after Grub (instead of the error message I got with the precompiled kernels), but otherwise booted fine. I just couldn't get them to display anything.
I think they put a lot of work into the Intel graphics driver in the kernel recently. That is why the error message dissapeared.

I think the screen blanking only comes after a pm-suspend. Usually when browsing the web. I tried both pm-suspend with and without --auto-quirks.

I don't think it has anything to do with Xorg.conf, since I both tried with and without one.

So it comes back down to the basic kernel. And I don't think I configured anything there at all, which leads me to think that it might be a real bug after all.

I did check for a bit if other people did report this already, but didn't find anything matching my problem very good. Could you keep the bug open for recent kernels please? Maybe someone else will come forward with the same problem.

I will see about 2.6.33 from experimental. My internet connection is currently a little slow, so I might only do this in a week or two.

Thank you so far for bearing with me.

Malte
