Arch Linux

Description:

I'm running two TITAN Xp GPUs with nvidia driver version 418.56-2:

on Arch Linux x86_64, Kernel: 5.0.4-arch1-1-ARCH :

.o+` ----------

-osssssso. :ssssssso. Memory: 1220MiB / 64098MiB


When I execute nvidia-smi I'm getting all the information about both of the GPUs:

+-----------------------------------------------------------------------------+

+-------------------------------+----------------------+----------------------+


But when I execute P2P bandwidth test sample from cuda package

/opt/cuda/samples/1_Utilities/p2pBandwidthLatencyTest/p2pBandwidthLatencyTest

my system hangs.

There was not the issue in nvidia driver 415 and kernel 4.20.

Steps to reproduce:

1) cd /opt/cuda/samples/1_Utilities/p2pBandwidthLatencyTest/
2) make
3) ./p2pBandwidthLatencyTest
