Is there any other information for this issue?
Are you using devkit?
Is it a pure package from jetpack? or have you modified the kernel?
How to reproduce this issue?
Nope, we are on a self-designed hardware platform, several Xavier inter-connected through a PCIe switch.
We did some modify about the kernel, but touch nothing about nvgpu driver.
Currently, this issue do not reproduce, we are trying to figure out the reproduce condition.
Thanks.
I have the same problem in xavier
Hi collpym,
Please file a new topic for your issue with more details, such as the reproduce steps, BSP info…etc.
Thanks
