first one has me stumped
I have two 128mb 4k owc dimms. When they are interleaved under macOS they are fine. I can go days without a crash. In linux, If I interleave them I start getting crashes and errors (pmon? debugger) almost immediately upon bootup. Can't figure it out. I would think this would be handled by the memory controller and therefore transparent to the OS. Two guesses. First is that the rams aren't that good quality and for whatever reason linux pushes the timing were the macos is a little more leanient. Second is that for whatever reason the macos needs to "know" they are interleaved and acsess them differently. This second one just sounds stupid but that's all I'm left with. So my 8500 crashes under linux with the ram interleaved but run fine in the MacOS.
Second problem is a kernel bug and I'm not sure how to go about taking care of it. This occures in all version of the 2.4 kernel and I've seen it on two machines. My current 8500 and my older Umax J700 (8500 Clone). The nice thing about it is that it only occures when I shutdown (so I don't). After all of the services shutdown and when the kernel brings down the built in ethernet I get a kernel panic. Something about mace transmit timeout. I'm first dropped into the debugger and then when I exit the kernel panics.
Beyond these two minor annoyances ydl works beautifully on this machine.
