I am trying to get an Interlan interface working on a PDP 11/70 under 2.9BSD. As soon as the Interlan board gets some host memory to DMA stuff into, the system goes to pieces. I haven't done a board swap yet, but I doubt that is the problem. This code worked on an 11/45, so I suspect a problem witht the UNIBUS mapping code in the network buffer management. Nothing glaringly obvious jumps out of the code (yet), so I assume that the bug is subtle. Ok there, 2.9 fans! Surely someone has invented/fixed this wheel already, so help would be appreciated (Not that I don't LOVE kernel memory management debugging :-]). -Clyde Hoover -- Shouter-To-Dead-Parrots @ Univ. of Texas Computation Center; Austin, Texas "Forward my mail to the corner of Pork and Beans" clyde@ut-ngp.ARPA, clyde@ut-sally.ARPA ...!ihnp4!ut-ngp!clyde, ...!allegra!ut-ngp!clyde
