I'm trying to get A/UX 3 stood up on my IIfx, and I'm running into a really strange problem - if the only Nubus card in the machine is my graphics card, it'll boot fine and run happily. If I add any more cards, it hangs at a grey screen with square corners, immediately after loading the kernel (I assume this is the point where A/UX Startup hands off control to the kernel). If I remove the cards again, it boots just fine. Swapping cards around between slots doesn't seem to change things either.
I first noticed this happen with a National Instrument GPIB card, I assumed that it was just a quirk with that particular card and removed it. But over the weekend I tried to add an ethernet card (an Asante MacCon 3 NB) and ran into the same problem. According to some old Usenet posts I dug up, and a few mentions on this forum, that card should be supported under A/UX.
Both the GPIB card and the Ethernet card seem to work just fine on System 7.1.
I guess it *could* be the machine itself, but I did have a working A/UX 3.1 installation running on it about 10-15 years ago (with almost a full complement of NuBus cards!). It's spent most of the intervening years in storage, but when I recapped it recently, I didn't notice any visible damage to any traces. Power supply voltages are all correct and appear to be stable.
I'm using a BlueSCSI as my disk drive, and the A/UX image from https://mega.nz/folder/8hA3AQCJ#pWUq92L70yDXlogy9lk5Dg (which I found linked in the BlueSCSI Github wiki). I also tried a clean install from an A/UX 3 ISO that I've had kicking around on my computer for years, with the same result.
Unfortunately I don't have any additional cards to test it with, but has this happened to anybody else? Any ideas where I should look?
