Yes. My guess at the moment is something involving acpi or the cpu frequency
daemon (acpi=off being one test to do). The reason for this is that when the
CPU changes speed it has to disconnect from the system busses and reconnect.
Thats a complex process and there are chip errata (and also maybe software
bugs of course) in this area which might foul up a current DMA transfer.
