cannot load the driver: Invalid parameters while run ./insert.sh about gdrcopy HOT 6 CLOSED

@sharan013 what if you make the following change?

diff --git a/gdrdrv/Makefile b/gdrdrv/Makefile

then try to build and install it:

@drossetti, that patch pointed out that I was picking up old driver sources. Thanks!

@hanyunfan that is strange.
Was that a clean build, i.e. from a pristine directory ?
Which linux kernel ?
Which NVIDIA driver ?
Can you copy here the relevant lines of the system log ? e.g. on RH/Fedora, 'dmesg |tail -20' should be enough.

from gdrcopy.

@drossetti Thank you for your reply.
It was a clean build on RHCE 7.2 64bit with cuda driver 370.25 and 4x P100 GPUs.
It's going to be hard to find the dmesg info after a month, but I will try to reproduct it asap.

The issue was gone.

I am using cuda7.5 on driver version 384 and GeForceGT640 on Ubuntu14.04.
