Issue Description
I was trying to use rawsocket and poll() to receive data from ethernet interface mgbe1_0. After the execution of my program, itseems to be crashed. After i kill my program, I just get this odd error message in my terminal. After a while the system halt and i need to reboot the system. My codes work fine in the other device.
Here is the error message:

[  799.713571] BUG: workqueue lockup - pool cpus=2 node=0 flags=0x0 nice=0 stuck for 37s!

Dear @rlu1,
Could you test using latest release i.e. DRIVE OS 6.0.10?

4

am i supposed to use the latest one? according to the document of drive OS, my board with the certain Part Number (P/N) is required to use the version 6.0.4.0

5

Are you referring to DRIVE Platform Supported Boards | NVIDIA Docs ? May I know the P/N?

Dear @rlu1 ,
Can you give a try flashing latest release with docker?
The other board is also same P/N?
Could you share repro code/steps?

8

i only have one orin board. I send message to the orin board through the 10GbE port. I think i will flash the latest release.
Unfortunately, i cannot share the code here.

9

should I uninstall the drive in my Orin board or should i do anything elese before I do the flashing?
According to the documentation( Set Up DRIVE OS Linux with NVIDIA GPU Cloud (NGC) | NVIDIA Docs), it seems there is nothing i need to do before except download the image on my host machine.
currently, I only have windows machine. Is that also okay? I already tried the container with DRIVE OS 6.0.4 with SDK before but not flashing the OS to my board.

Dear @rlu1 ,
You need Ubuntu 18.04/20.04 host to download the docker and flash. Please see Requirements for Your Development Environment | NVIDIA Docs and Install DRIVE OS 6.0.10.0 for NVIDIA Developer Users | NVIDIA Docs

Thanks for the reply.
windows machine does not support flashing even with docker desktop?
I previously pulled the docker image before and successfully ran the docker image on windows with docker desktop.

12

No. Ubuntu machine is required to flash the target.
