Hello Brian,

With this being a variant of Fedora, filing a Bugzilla was the right thing to do.  I missed that in your first email.

I checked your lspci output and ASPM *is* disabled as it should be.

When the adapter crashes/resets (per the log) does it come back up or stay down?

Since you're downloading off the Fedora build site, you could be encountering any number of things as these are live untested builds at this point.

Can you download a vanilla upstream build from kernel.org complete and see if the problem is happening there?  Or, you can download the latest released Fedora 14 from fedoraproject.org and see if the problem is happening with that build.  

Let me know how it goes,

Thanks,

Carolyn
