Issue running any workload on rooted Pixel 6 (Android 13)

[ghost]

Hi, I wanted to use this tool to run some workloads on my rooted Pixel 6 (Android 13), but every benchmark has an error:

ERROR    Module "cgroups" failed to install on target: Failed to mount "cpuacct" controller
ERROR    Failed to mount "cpuacct" controller

All of this occurred when I was running: wa run dhrystone -f
As for the run log, it comes up like this:

I was hoping maybe someone could help with a solution. Thanks!

Hi, It looks like the cgroups module (which is loaded by default) is having issues with your device (we have had similar reports with another Pixel 6 ARM-software/devlib#611)

If you do not explicitly need this module you can disable the default set and re-enable any you may require for your experiments.

To do so, could you try adding the following snippet to your agenda and see if this allows your run to execute correctly?

config:
    device_config:
        load_default_modules: False

Wow thanks for the quick response!
That worked right away.
There were some warning messages, but the workload completed.
Thank you so much!

Great, no problem and thanks for confirming.
Please let us know if you run into any other issues.
