Hello *.
Problem:
As soon as 64-bit nvdia driver is used on a Opteron / Asus SK8N System with SATA disks applications get only 10 % CPU performance left KDE / Grafic performance gets down ...
strange: there are a great number of NMI's showing up: NMI: 11979329
cat /proc/interrupts: 11: 1003701 XT-PIC NVidia nForce3, nvidia
Model: GeForce FX 5950 Ultra IRQ: 11 Video BIOS: 04.35.20.36.00 Card Type: AGP
Questions:
-someone has a Asus SK8N working with hardware accelerated open gl capable agp-card ? are there other 64 bit supported opengl cards recommended ?
-kernel options like noacpi or bios settings concerning agp did not change the problem anyone hints what causes the conflict ? ( irq or agp problem assumed)
Yesterday I had a problem which *might* relate. It concerned the latest nVidia driver for a GeForce FX 5700 Ultra but this was on a dual Athlon MP box. Application performance would seriously degrade as the X server began consuming large percentages of CPU cycles. Just to get the things back in a more reasonable state, I had to disable AGP as discussed in nVidia's README (link below). I am still investigating. ftp://download.nvidia.com/XFree86/Linux-x86/1.0-5336/README The xf86config Option "NvAGP" "integer" relates. If applicable to you, you might try -> Option "NvAGP" "0" <- for the nVidia driver in XFree86Config. If that helps then look at Appendix F in the above README for more detail. It could be necessary to change how the kernel is compiled in order to re-enable AGP; someone else can better discuss since I am not very knowledgable of the involved graphics issues. Bill
