I continue to see the same behavior. Sometimes networking lasts a few hours, sometimes over a week, typical is dying after 4-5 days. I have found no way to restore it but rebooting.
I have not tried switching to Jaunty, but I did upgrade to the latest kernel on kernel.org, and the behavior continues. The last run lasted just over a day on 2.6.30.4 before poof it was gone. Other errors I see in the logs: MAC is in deep sleep!. CSR_GP_CNTRL = 0xFFFFFFFF and Failed to init APMG and HARDWARE GONE??
