Problem: during a period of relative inactivity (middle of the night), the system crashed. I've got kernel trace output in the logs that point towards the sky2 driver (see below). The errors were for eth0, eth1 (dual-nic motherboard) was unaffected. There were no relevant log messages indicating anything abnormal prior to the time of the initial kernel trace. A Subsequent to the trace, eth0 was bouncing up and down (Fedora network manager kept trying to bring the network back up). Each time the adapter came back up, I see DHCP Discover, offer and ack messages for each connected device. It appears that the link would go back down before the completion of DCHP activity. The only trace is for the first event; subsequently, I just see sky2 eth0: tx timeout; disabling interface and enabling interface messages. Oddly, this cycle continued for one hour (down to the second), at which time the system rebooted. There were no messages indicating anything about final reason for the reboot.
