Hi, can you try the attached patch (relative to RELENG_5). It disables batch transfers from the system queue to the driver - an optimization introduced while enabling rl(4) for ALTQ. Please let me know if it improves the situation. If it does, this is a sign of a more fundamental problem in the driver locking (or the card timing) and needs further evaluation.
Thanks.
