Try updating to 5-STABLE. This is likely due to bugs in the >4GB
handling for bounce buffers that I fixed recently. Actually, on
closer look it might be that the isp driver is buggy also. Well,
updating to 5-STABLE is a requirement here anyways, so give that a
try and let me know if it's still a problem.
