And what *might* be happening (which would be *really* annoying) is if bus_dmamem_alloc is allocating something that spans pages, although I doubt that what you see would be the symptoms if this were the case.

It will only span pages if the allocation size is > PAGE_SIZE.

It doesn't (currently at 4096)- and I need to figure out how to make the bus_dma_tag_create call in isp_pci_mbxdma set things up so that you can at least *try* and get > pagesized allocations (maybe with the filter function- or maybe just try with a boundary limit and if you lose, you lose).
