this is with 2.6.0-test2, no devices attached to the bus, on UP. Is it a known problem?
No, hadn't seen it -- but then, last time I tried a CardBus adapter it had major PCI problems. It's been quite a while since I've seen those work correctly with 2.5 kernels, maybe since about 2.5.70.
If it's working for you even that well, it's significant progress. I'll see if it happens for me in recent test2 kernels.
