From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322) Description of problem: I have an Intel D945PSN main board with an integrated PRO 1000 gigabit Ethernet adaptor. After updating the system to kernel-2.6.15-1.1831_FC4 from kernel-2.6.14-1.1656_FC4 the onboard nic ceases to function properly. Attempting to ping or telnet to another host results in a network unreachable error. I observe a large number (50%) of receive overrun and frame errors on the interface with the new kernel. I thought there might have been a problem with the auto-configuration of the nic so I set the interface to 10Mb/s-HD which caused the frame errors to stop, but the problem still persisted. I noticed in the system log many of the following messages: Feb 11 11:14:21 atlas kernel: e1000: eth0: e1000_watchdog_task: NIC Link is Down Feb 11 11:14:25 atlas kernel: e1000: eth0: e1000_watchdog_task: NIC Link is Up 100 Mbps Full Duplex After rebooting back to the 2.6.14 kernel the ethernet adaptor operates normally so I think itâs safe to assume the problem is with the 2.6.15 kernel and the e1000 driver. Version-Release number of selected component (if applicable): kernel-2.6.15-1.1831_FC4 How reproducible: Always Steps to Reproduce: 1.reboot system into kernel-2.6.15-1.1831_FC4 or kernel-2.6.15-1.1830_FC4 2. 3.
