Just adding that I see this problem completely randomly - even when the drive does not have a disc in: let alone an encrypted DVD. My computer pretty much completely locks up when this problem occurs, therefore I cannot verify whether it is a HAL component which is hogging the CPU, nor can I find any other information acknowledging this error bar dmesg.
