Nvrng driver does not work when resume from suspend

Hello. I found issues about suspend/resume function with the reference document.

We get some driver error logs while doing resume from suspend on Orin generation. Those are not expected behavior. Could you please investigate and modify by nvidia’s bsp kernel team?

Error messages

  • nvrng error
    [   61.440872] PM: dpm_run_callback(): platform_pm_resume+0x0/0x80 returns -110
    [   61.440877] PM: Device 3ae0000.nvrng failed to resume: error -110

Reproduce step

  1. Turn on power
  2. echo +20 > /sys/class/rtc/rtc1/wakealarm; sleep 3; systemctl suspend
  3. Happen the above error message. It’s mean that nvrng driver does not work after resume.

Reproducibility is 100% (4/4)
