Strangely enough I would add that the problem doesn't occur on my work machine (Thinkpad P52s) with (almost) the same card:
em0@pci0:0:31:6: class=0x020000 card=0x225a17aa chip=0x15d88086 rev=0x21 hdr=0x00
vendor = 'Intel Corporation'
device = 'Ethernet Connection (4) I219-V'
class = network
subclass = ethernet
(only difference is "card=0x225c17aa" vs "card=0x225a17aa")
This problem doesn't occur anymore on 12.2 (and latest -pxx 12.1) |
Created attachment 209347 [details] sysctl dev.em Hello, On my Lenovo X1 Carbon 6th Gen the network interface jumps constantly from DOWN to UP when there is some traffic. Sometimes it completely freeze and only a reboot solves the problem: Nov 22 20:46:40 x1 kernel: em0: link state changed to DOWN Nov 22 20:46:43 x1 kernel: em0: link state changed to UP Nov 22 20:46:48 x1 dhclient[2805]: New IP Address (em0): 192.168.0.88 Nov 22 20:46:48 x1 dhclient[2806]: New Subnet Mask (em0): 255.255.255.0 Nov 22 20:46:48 x1 dhclient[2807]: New Broadcast Address (em0): 192.168.0.255 Nov 22 20:46:48 x1 dhclient[2808]: New Routers (em0): 192.168.0.254 Nov 22 20:46:49 x1 kernel: em0: link state changed to DOWN Nov 22 20:46:52 x1 kernel: em0: link state changed to UP Nov 22 20:47:00 x1 dhclient[2829]: New IP Address (em0): 192.168.0.88 Nov 22 20:47:00 x1 dhclient[2830]: New Subnet Mask (em0): 255.255.255.0 Nov 22 20:47:00 x1 dhclient[2831]: New Broadcast Address (em0): 192.168.0.255 Nov 22 20:47:00 x1 dhclient[2832]: New Routers (em0): 192.168.0.254 Nov 22 20:47:10 x1 kernel: em0: link state changed to DOWN Nov 22 20:47:12 x1 kernel: em0: link state changed to UP Nov 22 20:47:21 x1 dhclient[2856]: New IP Address (em0): 192.168.0.88 Nov 22 20:47:21 x1 dhclient[2857]: New Subnet Mask (em0): 255.255.255.0 Nov 22 20:47:21 x1 dhclient[2858]: New Broadcast Address (em0): 192.168.0.255 Nov 22 20:47:21 x1 dhclient[2859]: New Routers (em0): 192.168.0.254 (...)
