Dear All,
Can anyone suggest what kernel options are best for driving the board that appears in lspci as
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)
please?
(I think I've got the wrong ones, sice DPMS is flaky and I'm getting quite frequent kernel panics related to intelfb.)
Hi Dan,
Do you use X? I have Intel 945 in my desktop and use the stock Ubuntu kernel and let X do all the hard work.
Tim.

Yes. The DPMS flakiness has been going on for a while, and is described at http://www.mail-archive.com/xorg@lists.freedesktop.org/msg09263.html. The frequent kernel panics are new since I upgraded from 2.6.28 to 2.6.30. (This is all under Gentoo).
Thanks,
Dan

OK. I ditched the framebuffer support. The good news is my GUI still works. The bad news is that I'm still getting both the kernel panics and the DPMS flakiness. Reading back up the kernel panic messages, they mention both TuxOnIce and ath5k, the latter being mentioned in the same position (right at the end) that intelfb was mantioned before. Any ideas?

Now this is strange. As I said, I now don't have framebuffer support in the kernel (i.e. it's not compiled in, and the module, although available, is not loaded), yet today, I still got a crash with a message about "intelfb_panic".

In your previous message you mentioned ath5k which is a wireless driver and TuxOnIce which appears to handle hibernation. I'd therefore be inclined to try turning off wireless for a while and also trying without using hibernation to see if either of these solves the problem with the panic.
It is also worth running memtest86 to check for faulty memory - if there is a memory fault this can cause puzzling symptoms because, as the configuration changes, the module affected by the fault also changes.
HTH, Steve.

Just a quick update. On upgrade from the kernel known to Gentoo as 2.6.28-tuxonice-r10 to the one known as 2.6.33-tuxonice-r1, the kernel panics went away and were replaced by the known issue described at http://lists.tuxonice.net/pipermail/tuxonice-devel/2010-March/006000.html.
DPMS still flaky, though.
Many thanks to Steve and Tim.
Dan
