nvsound module doesn't work on newer kernels

[matejo]

I am running gentoo linux and I must upgrade the kernel to newer version (>2.6.12). Nvsound module works perfectly on gentoo-sources-2.6.12-r10.
But on newer kernels it crashes my machine.
I have tried 2.6.13, 2.6.14, 2.6.15 and 2.6.16 on which it compiles normally but when loaded it crashes kernel. Kernel oopses.
Sorry I cannot output the message because it doesnt log the error.

I am using GCC 3.4.4 and 1.0.0310 nforce drivers. The error is the same with previous version of nvsound module.

hi,

i'm running Gentoo Linux on my AthlonXP / ASUS A7N8X-E Deluxe / nforce2 MCP-T Hardware. Kernel 2.6.14-r5 and Kernel 2.6.15-r1 run with nvsound 0310 without any problems here.

I'm also using gcc 3.4.4

So it runs on newer kernels. This is nice to hear.
Now I just need to find out how to find out what seems to be the problem with my system...
What are your kernel settings? (General setup & Processor type and features)

Thank you. This solved my problem. I'm a linux-newbie but I think "IO-APIC support on uniprocessors" was what solved this problem.
