Hi,

This series and specifically the commit above broke docker over PPC.
It causes to docker service stuck while trying to activate. Revert of
this commit allows us to use docker again.

Hi,

there have been follow-up fixes, that are part of 6.4.3 stable (also
6.5-rc1) Does that version work for you?

Python script which we used for bisect:

import sys

    print('running:', cmd)

    try:
        stdout, stderr = p.communicate(timeout=30)

    except subprocess.TimeoutExpired:
        return True

    print(stdout.decode())
    print(stderr.decode())
    print('rc:', p.returncode)

    return False


def main():
    commands = [
        'sudo systemctl stop docker',
        'sudo systemctl status docker',
        'sudo systemctl is-active docker',

    for i in range(1000):
        title = f'Try no. {i + 1}'
        print('*' * 50, title, '*' * 50)

        for cmd in commands:
            if run_command(cmd):
                print(f'Reproduced on try no. {i + 1}!')
                print(f'"{cmd}" is stuck!')

            print('\n')
