Hello,

i'm using linux 2.6.0-test11-bk11 on Intel architecture (Celeron
Coppermine) and nvidia kernel module 1.0-4620 for Nvidia GF FX 5200.
Mttr registers are enabled.
I applied appropriate patches from www.minion.de.
After loading and using nvidia kernel module, dmesg shows this output:

nvidia: module license 'NVIDIA' taints kernel.
0: nvidia: loading NVIDIA Linux x86 nvidia.o Kernel Module  1.0-4620

agpgart: Putting AGP V2 device at 0000:01:00.0 into 4x mode

This always is happening on loading this module.
I get same trouble with nvidia kernel module 1.0-4496.
I never had such problems with kernel 2.4 before.

Any suggestions?

With best regards,
Lukas

I get these messages all the time with nvidia module, you can disable
these messages from the kernel configuration: "make menuconfig -> kernel
hacking -> sleep-inside-spinlock checking"

You pribably didn't have that option enabled in the 2.4 kernel.
I don't know about the danger of this message, but it haven't caused me
any problems
