Thanks! I appreciate you getting back to me. I've got about 30 huge bugs I am shaking down, and this one just cropped up, so I haven't been able to put a lot of time into it yet. I rolled a full debug kernel last night to troubleshoot what appears to be a spinlock/mutex issue with something else, but I'm sure it'll help with this too.
If I find anything out I will also reply with the details....

My last working kernel on this was a 2.6.x, it's been a while since I've had time to bring this system up to date, so I don't know when this may have started. I had a 3.0.102 in there, but I didn't test the networking while using it.
Please let me know what I can do to help out with figuring this one out.
I don't have an Alpha machine to try this on, but I do have a functional Cobalt Qube2 (MIPS 32/64) with these adapters connected directly over PCI:

the machine is not currently on a switch that I can control, but I can certainly try to plug in the cable and see what happens, give me a couple of days to get back to you, and if you don't hear back, please holler. Here are the bits of kernel configuration:
CONFIG_NET_TULIP=y CONFIG_TULIP=y # CONFIG_TULIP_MWI is not set # CONFIG_TULIP_MMIO is not set # CONFIG_TULIP_NAPI is not set
