Driver causes mouse cursor to dissapear on GeForce 6600 PCIe card

[JakeN1]

I have been using the FreeBSD nvidia driver successfully for a while now, on an older AGP based GeForce 440. However, I recently upgraded the system to a PCI -Express based motherboard and GeForce 6600 card.

Since then, the system has been very unresponsive - the mouse cursor dissapears whenever it is not over the desktop, or when it is moved quickly. This doesn't happen using the "nv" driver. I would rather use the native driver, however - due to the 3D acceleration support.

Details are:
Motherboard: ABit AW8-MAX
Card: PCI-Express 6600 :
Jun 28 01:02:19 asbo kernel: nvidia0: <GeForce 6600> mem
0xfa000000-0xfaffffff,0xd0000000-0xdfffffff,0xfb000000-0xfbffffff irq 16
at device 0.0 on pci1
Jun 28 01:02:19 asbo kernel: nvidia0: [GIANT-LOCKED]
Monitor: Sony GDM 500PS (CRT)
OS: FreeBSD 6.1 RELEASE

My xorg config is attached. I have tried setting NvAGP to 0... can anyone suggest anything else?..


Thanks - Jake

Looks like the forum's quiet at the minute. I resolved this last night, though. It turned out to be an IRQ conflict - "systat -vmstat" showed bge interrupts at a rate of 70'000 per second. One of the NICs and the graphics card were using the same IRQ; disabling the NIC solved the problem.

I am curious how I would go about solving this problem if I actually needed to use the NIC in question - I haven't had to deal with IRQ conflict since they were set manually with jumpers!
