kern (1).log (431.3 KB)
Hi,
We use Jetson AGX Xavier. L4T version is R35.6.0. A carrier board we designed ourselves.
After a soft reboot (at 17:44 on May 26), the system froze for approximately 10 minutes. It was only after 10 minutes that the system rebooted normally. The PMC displayed the following reason for the reboot: tegra-pmc: ### PMC reset source: BCCPLEXWDT.
After executing the reboot command, the kernel printed the following error message and then froze:

See the attachment for detailed kernel logs.
We want to know why the system freezes when we run the reboot command, and why we have to trigger the BCCPLEXWDT watchdog to restart it.
