Random crashing - Nvidia drivers issues with Hardy - Solution!

[db260179]

Hi people,

If you are experiencing random crashing, instability and own a Nvidia Graphics card. Using a x2 core processor can be affected and ATI cards suffer from a suspend/resume issues.

Then you will need to compile your own kernel, as the current hardy kernel has settings that causes these problems.

Let me explain my findings (please note: it doesnt affect everyone, but of the two pc's i own, 1x has the problem)

1. The Kernel has a schedule set to SLUB not SLAB (SLAB is more compatible and reliable with NVidia and ATI drivers)

2. If using your custom kernel - the ubuntu-restricted modules doesnt compile properly - nvidia names the modules wrong, thus unable to get driver to load.

I have a custom kernel using hardy kernel source that i made, for i386 and amd64. Message me if you wish to prove my statement or have a pc having problems.

Thanks! Did you report your findings as a bug in launchpad?

Oops, will do! - also as a last note: cool and quiet causes problems as well!

Creates NVRM: errors, hard locks

This was an issue a while ago, but nVidia has since fixed the problem; nVidia's driver now lives happily with SLUB. However, after installing the driver like normal, there's a few more things to do to get suspend working. (http://blog.vaxius.net/?p=43) (That's a link).

Thanks for that tip!

SLAB stills works better for me.

Also i missed out another issue with the nvidia driver - turning on the cool and quiet feature in the bios causes problems. On my Asrock HDready 7G board.

Further testing - i've turned the cool&quiet back on, and turned off the powernowed service. No lockups so far. obviously this issue is still here with the powernowed service.
