Per the arb-bridge-eth code:
At L308-L309, ETH held by BridgeMinter is withdrawn to L1Migrator:
https://github.com/livepeer/arbitrum-lpt-bridge/blob/ebf68d11879c2798c5ec0735411b08d0bea4f287/contracts/L1/gateway/L1Migrator.sol#L308-L309
However, when calling sendTxToL2() the parameter _l1CallValue is only the msg.value, therefore, the ETH transferred to L2 does not include any funds from bridgeMinter.
https://github.com/livepeer/arbitrum-lpt-bridge/blob/ebf68d11879c2798c5ec0735411b08d0bea4f287/contracts/L1/gateway/L1Migrator.sol#L318-L327
As a result, due to lack of funds, call with value = amount to l2MigratorAddr will always fail on L2.
Since there is no other way to send ETH to L2, all the ETH from bridgeMinter is now frozen in the contract.
