https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=243319 --- Comment #6 from Conrad Meyer <cem@freebsd.org> --- These are different requesters? It would help to spell out which IP(s) are the panic'd laptop. 07:55:53.025959 ARP, Request who-has 10.6.112.1 tell 10.6.112.16, length 46 07:55:53.025980 ARP, Request who-has 10.6.112.1 tell 10.6.112.18, length 46 ^^ If you don't have debugnet enabled I don't see any obvious reason debugnet would be ARPing. Plus, debugnet isn't *that* spammy and the number of ARPs it sends is bounded; it gives up after a few tries (like, 3?). You would see obvious prints as a side effect of debugnet-enabled dump being attempted after the panic, and an obvious print when the ARP request failed. If anything, I suspect this is some NIC internal firmware/hardware behavior due to the panic'd machine not processing RX queues or something. -- You are receiving this mail because: You are the assignee for the bug.help
