I have a network watchdog script, that should only run after suspend, as the sky2 driver sometimes hangs after resume. It tries to do a DNS lookup and re-initializes the interface (ifdown, rmmod, modprobe, ifup) if the lookup failed. But no activity here at that time: 2007-06-22_04:47:54.31644 Server: 10.100.1.254 2007-06-22_04:47:54.32896 Address: 10.100.1.254#53 2007-06-22_04:47:54.32897 2007-06-22_04:47:54.32898 Name: mguard.home.local 2007-06-22_04:47:54.32899 Address: 10.100.1.253 2007-06-22_04:47:54.32899 2007-06-22_08:47:04.15808 Server: 10.100.1.254 2007-06-22_08:47:04.17365 Address: 10.100.1.254#53 2007-06-22_08:47:04.17366 2007-06-22_08:47:04.17367 Name: mguard.home.local 2007-06-22_08:47:04.17368 Address: 10.100.1.253 2007-06-22_08:47:04.17369 > another possibility is suspend/resume. A resume happened at 4:47: 2007-06-22_04:47:31.51073 kern.debug: Back to C! So the above disabling interface/enabling interface was in the middle of normal operation.
