Do you have any other drivers in your kernel that might be looking at iospace 0x2c0-0x2df. Also, did you know that both of these cards have the same memory address. I don't think that matters for the ne2000 since they don't do memory mapped I/O. Areas that would cause this: New drivers changed drivers changed configure code (kern/subr_bus.c) whacked out space aliens messing with your mind Resource allocation plug and play Now, one of the above list is almost certainly not right, but as for the rest... You might try updating the filesystems and vm to 4.1.1 from 4.1. I'd expect 0 effect by doing that. Beyond that, I'm not quite sure what to suggest. This is weird, eh? Let's see. Looking at the logs, I'd say that July 26th to September 25th is the target range. I'd do a binary serach over that time frame for the kernel as a whole. Two months shouldn't take more than 6 or 7 kernels to track the problem down with to a given day and maybe 2 or 3 more to find the change that broke things. I'd also be tempted to try Sept 9th first, since that's the day before the MFC of the ed driver and something tells me that it is a good place to start.
