The 3.10 kernel is End Of Life, can you reproduce with a later kernel. This looks like a network driver specific suspend/resume bug. You need to describe the identify the network driver (lspci or ethtool). *** This bug has been marked as a duplicate of bug 196399 *** The only network device listed is the Intel Wireless card. Please contact the Intel wifi team. >can you reproduce with a later kernel This is a kind of bug I cannot reproduce intentionally (it just happened without my attention, I don't know how to trigger it on purpose). Also, it happens very infrequently (first time this month), so "sit and wait" method can't be used here either. >The 3.10 kernel is End Of Life Sure, but (1) it ended quite recently, (2) I have no proof that this bug was fixed in newer kernels. >The only network device listed is the Intel Wireless card. I doubt I have any wireless cards in my server.
