I just updated to 7-RELENG using csup and compiling from source a machine that had been happily running with a Intel PRO/1000 GigE card on 7-PRERELEASE Building went fine, but as soon as I booted multiuser, I had my network connection go up and down like a Yo-Yo. Here is an excerpt: Mar 7 16:34:40 kreacher em0: link state changed to UP Mar 7 16:34:40 kreacher em0: link state changed to UP Mar 7 16:37:52 kreacher em0: watchdog timeout -- resetting Mar 7 16:37:52 kreacher em0: link state changed to DOWN Mar 7 16:37:52 kreacher em0: link state changed to DOWN Mar 7 16:37:56 kreacher em0: link state changed to UP Mar 7 16:37:56 kreacher em0: link state changed to UP Mar 7 16:38:08 kreacher em0: watchdog timeout -- resetting Mar 7 16:38:08 kreacher em0: link state changed to DOWN Mar 7 16:38:08 kreacher em0: link state changed to DOWN Mar 7 16:38:12 kreacher em0: link state changed to UP Mar 7 16:38:12 kreacher em0: link state changed to UP Mar 7 16:38:22 kreacher em0: watchdog timeout -- resetting Mar 7 16:38:22 kreacher em0: link state changed to DOWN Mar 7 16:38:22 kreacher em0: link state changed to DOWN Mar 7 16:38:26 kreacher em0: link state changed to UP Mar 7 16:38:26 kreacher em0: link state changed to UP Mar 7 16:38:33 kreacher em0: watchdog timeout -- resetting Mar 7 16:38:33 kreacher em0: link state changed to DOWN There was nothing else stressing the system at the time. The load average was around 0.25 on a dual core system. Everything works fine if I use the on-board nfe ethernet port on the machine, but I would like to get Gigabit ether back working on this machine. I don't really know what sorts of information I need to be looking at or reporting. Any advice would be welcome. The only change on the system for many weeks has just been my move to 7-RELENG today which appears to have triggered the problem. Cheers, -j
