I'm running 2.2.2-RELEASE. I have 32M of RAM. I have bounce
buffers in my config. The SCSI controller is an Adaptec 1540. It
dumps 16M and then at the 16M boundary complains about DMA beyond
end of ISA and stops dumping. Any ideas?
Config and boot messages appended (from a run with 16M, where I
can get a complete dump).
