nv quadro nvs140M crashing

[mulaz]

i have a nvidia quadro nvs140m in a thinkpad R61i (8918-CJG) on gentoo linux with 2.6.23-r3 kernel
i'm using nvidia-drivers-100.14.19 and I am experiencing random crashes when running 3d apps

i first noticed it on googleearth, it seems to work fine for a couple of minutes, but then it locks up, and the system becomes unresponsive for almost anything. Usually pressing the on/off button triggers the shutdown.

in /var/log/messages i get:

It's funny, becouse sometimes i can run googleearth with 3d buildings on, and two glxgears over it for an hour with no problems. And when i close those, and after some time it can crash just if i run one glxgears.
I also use 'pci=nommconf and idle=poll' wen i boot, but it doesnt help. I also updated the bios, and no changes.

It's also interesting that if i downclock the gpu (using coolbits in the .conf and nvidia-settings) to half the frequency, it gets more stable (almost impossible to crash).
Thermal monitor shows 53˚c, but since applications cause crashes immediately when they start, (i guess) it's not an overheating problem.

If anyone has any experience with that, please help.

thanks

Did you test with the latest driver?
I don't experience any crashes.

interestingly enough, i never noticed gentoo didnt have 169* versions included
i'll write en ebuild for it, and I will report if the crashes continue (since it's hard to predict when it will happen)
