config LOCKDEP_CHAINS_BITS
        int "Bitsize for MAX_LOCKDEP_CHAINS"
        depends on LOCKDEP && !LOCKDEP_SMALL
        range 10 21
        default 16
        help
          Try increasing this value if you hit "BUG: MAX_LOCKDEP_CHAINS too low!" message.

Can you increase the chain bits config and try again?

Thanks,
