nvidia card and kernel 3.1

[Dmitriy Tochansky]

Hello!
I bough new videocard yesterday and have some problems with it.
After inserting it to my PC, I found in dmesg:

Much other problems like:
[root@home toch]# modprobe fuse
FATAL: Error inserting fuse
(/lib/modules/3.1.0-7.fc16.i686/kernel/fs/fuse/fuse.ko): Cannot allocate
memory


Boot with kernel 3.3 is failed with blackscreen.

Looks like something ate the whole vmalloc space.
Maybe nouveau is over-allocating. Can you file a bug, and attach the whole dmesg please ?

I worked around this problem with "acpi=off" parameter in
grub. I can
reproduce this problem later, when come back home.

I doubt we're over-allocating.  However, NVIDIA GPUs have *huge*
register BARs that we need to map.  We already limit the size of the
mappings to what we can reasonably manage without making the code
extremely convoluted.

The problem will be worse with the NVIDIA binary driver, they map the
entire BAR0 (16MiB usually, 64MiB on some cards) and BAR3 (16MiB/32MiB
depending on the card), always.
