Reading the documentation (ie. source code) it appears the problem is
triggered by the line
Looks like the driver calls pci_find_subsys() from inside an interrupt on
occasions which apparently it shouldn't. The problem seems to be on
nvidia's side, not kernel development. I have emailed nvidia about it some
time ago, so far no reaction...
I got the problem with nvidia modules 4496, 5328, 5336 and with kernels
2.6.0, 2.6.1, 2.6.2, never with 2.4.X. I have stopped using the nvidia
kernel module for now.

Is this www.nvnews.net you are talking about? I can't find any proper
contacts on the nvidia web site. I'll go over and add a comment right
