I've been observing very similar behavriour with recent 6.2-STABLE on
i386 with either Silicon Image 3114 or Promise FastTrak TX4. gmirror
synchronisation worked OK until I've added some additional load on the
synchronised volume. Unfortunately I haven't been able to take any
reasonable DDB output :-(
