Re: "PCI: Cannot allocate resource region" messages at boot

[D. Sen]

I tried it out but the patch doesnt seem to make any difference.

I see those messages before any attempt to load the yenta/pcmcia socket 
models. It has to be something else, I would think. Following is the 
sequence of messages at boot time (the messages appear whether or not I 
load pcmcia modules):

Thanks for the suggestion though.
