re(4) had long standing bus_dma(9) bugs. I think I fixed most of
bus_dma related bugs in 7-stable. Some users still suffer from
instability issues but I guess it's different one that came from
lack of documentation of PCIe based controllers.
If you are not running 7-stable, try it 7-stable first and let me
know how it goes.
