Hi Michal,

The issue happened again, but the /proc/1/stack and 
/proc/$pid_of_dbus-broker/stack are both empty on our platform.

I checked kernel config and confirmed that  CONFIG_STACKTRACE is enabled:

zcat /proc/config.gz | grep CONFIG_STACKTRACE
CONFIG_STACKTRACE_SUPPORT=y
# CONFIG_STACKTRACE_BUILD_ID is not set
CONFIG_STACKTRACE=y

Is there any other config that is missing?

Thanks,

Heyi
