OK, last fix to olympic enabled a subtle bug to surface when network_monitor was enabled.The bug has been there all the time, but before the last patch the problem (an out of bounds mmio write) was ignored.
I'm going to wait a little while before sending this one off, with all the patches floating around at the moment, the previous updates haven't fully percolated into the final kernel releases. Once its there, I'll update with the patch. If you've having the problem, simply turn off the network_monitor mode in the interim.

Still have the issue with the cardbus adapters on certain thinkpads, this is not a pleasant one to hunt down. I don't have a thinkpad to emulate the problem with and working with somebody who does via email is tough. I'm still not convinced that the cardbus controller/subsytem isn't to blame somewhere along the line.
