OPTEE vs GCC 12.X.Y

Hello everyone,

I’m using Jetpack 5.0.2/ L4T R 35.1 and I’m building OPTEE (OS, Client, Samples and Test) from sources Linux_for_Tegra/source/public/nvidia-jetson-optee-source.tbz2

I’m using GCC version 12.2.0 . When running the xtest (OPTEE test suite), I noticed the CPU hangs for a moment then system reboot

Kindly see the logs below:

��[  368.162281] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks:

Any idea about the cause of the CPU hanging ?

Any help would be appreciated.
Best regards,
