AGX Xavier reboots after 1 core cpu loads 100%

Could you check the CPU usage is still 100% for 640x480 output size?

It works near 5 hours and CPU does not load 100%.
Also, I try to run some examples from /usr/src/nvidia/graphics_demos and it’s not load CPU and no reboots

Right now i want to try argus_camera --outputsize=640x480 with multiple session

argus_camera --outputsize=640x480 freezes too (multiple session).
I find same pretty same problem vithout solution here: Argus errors with high cpu load and subsequent issues - #24 by SanjayD

Logs same:

Jan 27 11:52:55 jetson nvargus-daemon[6225]: (Argus) Error InvalidState:  (propagating from src/api/ScfCaptureThread.cpp, function run(), line 109)
Jan 27 11:52:55 jetson nvargus-daemon[6225]: SCF: Error InvalidState: Session has suffered a critical failure (in src/api/Session.cpp, function capture(), line 667)

PS. I see what syslog file is large

I’m try to start my opencv gstreamer example and all works well vore 4 hours, but when i connect wifi usb adapter it freezes.
Syslog here: (before HDMI reconnection)
err.txt (230.5 KB)

I try to restart stream when usb wifi adapter was connected and Jetson reboots. Log here: after Jan 28 02:11:28 jetson kernel: [19699.847822] imx390 32-001c: imx390_set_gain: db: 84

It can be interesting too. Syslog before reboot. At now Errors in nvargus_daemon. Here I’m turn off time synchronization (do-timestamp=false)

@ShaneCCC Any ideas?

Could you try below command before run the camera.

I find problem in bluetooth hostwake (cpu irq). How to turn off it forever?
I try disable bluetooth.service but it not help
I try this:

sudo modprobe -r bluedroid_pm

but it works before reboot

Do you have idea to disable buletooth interrupt for debug.
Or any experience for bluetooth cause CPU loading?



You can directly remove bluedroid_pm.ko file from /lib/modules.

So, I’m add install bluedroid_pm /bin/false into /etc/modprobe.d/blacklist.conf.
It can stop this module and dependencies. Works well.

Thank You for Your help @ShaneCCC @WayneWWW !

BTW, could you check if jetpack4.5 also has this issue on your board? This should be resolved on jp4.5.

I can not because camera drivers with conecttech gmsl board available for JP 4.3 and 4.4 only

I add a repo with a description of all fixes for the camera work.
Hope it helps other developers

Can you help me stop bluedroid_pm please

install bluedroid_pm /bin/false into /etc/modprobe.d/blacklist.conf.

I don’t understand what to do here?


sudo nano /etc/modprobe.d/blacklist.conf

paste string: install bluedroid_pm /bin/false

Thanks @kuskov.stanislav. I can confirm that on our stock AGX Xaviers, disabling bluedroid_pm (which is actually a NVIDIA bluetooth power management driver) via the following successfully solved the random reboot issue as well reduced CPU usage:

$ sudo gedit /etc/modprobe.d/blacklist.conf

> Add the following lines at the end of the file that opens:

# Disable bluetooth power management driver to fix random crashes/reboots and high CPU load
install bluedroid_pm /bin/false
