https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258057 --- Comment #31 from Dan Kotowski <dan.kotowski@a9development.com> --- I've been able to trigger this behavior as well from Firefox by reloading ~= 20 tabs at once, even when I'm able to get the device to negotiate superspeed. ugen1.8: <Microchip LAN7800> at usbus1, cfg=3D0 md=3DHOST spd=3DSUPER (5.0G= bps) pwr=3DON (224mA) ugen1.8.0: muge0: <Microchip LAN7800, rev 3.10/3.00, addr 8> Something I noticed as that when the interface begins flapping, IPv4 will sometimes remain partially usable but IPv6 fails entirely. I'm not sure if = it's related, but I also regularly see this in /var/log/messages: lock order nd6 list -> lle established at: #0 0xffff0000004e3368 at witness_checkorder+0x438 #1 0xffff000000470574 at _rw_wlock_cookie+0x74 #2 0xffff00000064ba14 at nd6_llinfo_timer+0xa8 #3 0xffff000000493260 at softclock_call_cc+0x13c #4 0xffff00000049356c at softclock+0x44 #5 0xffff0000004329a0 at ithread_loop+0x2a8 #6 0xffff00000042efa8 at fork_exit+0x74 #7 0xffff00000077bbc4 at fork_trampoline+0x14 lock order lle -> nd6 list attempted at: #0 0xffff0000004e3b3c at witness_checkorder+0xc0c #1 0xffff000000470574 at _rw_wlock_cookie+0x74 #2 0xffff000000651a20 at defrouter_remove+0x40 #3 0xffff00000064e7c0 at nd6_na_input+0x848 #4 0xffff0000006244cc at icmp6_input+0xd2c #5 0xffff00000063d078 at ip6_input+0xe5c #6 0xffff0000005b4044 at netisr_dispatch_src+0xe4 #7 0xffff0000005980ac at ether_demux+0x174 #8 0xffff000000599734 at ether_nh_input+0x3f8 #9 0xffff0000005b4044 at netisr_dispatch_src+0xe4 #10 0xffff000000598584 at ether_input+0x80 #11 0xffff0000002f2b50 at uether_rxflush+0x8c #12 0xffff0000002e1778 at muge_bulk_read_callback+0x120 #13 0xffff0000002dd9a0 at usbd_callback_wrapper+0x6b0 #14 0xffff0000002decb0 at usb_command_wrapper+0x124 #15 0xffff0000002ddb38 at usb_callback_proc+0x30 #16 0xffff0000002d8c6c at usb_process+0x10c #17 0xffff00000042efa8 at fork_exit+0x74 --=20 You are receiving this mail because: You are the assignee for the bug.=
