Created attachment 201549 [details] dmesg from 11.2 After upgrade from 11.2 to 12.0 my network stop to work. Network cards get addresses but data exchange does not occur. I tried a clean install, but the situation has not changed. I have only 11.2 dmseg, because had to rollback quickly.
Unfortunately, there isn't really anything to go on here. I don't see any network-related error messages in the attached dmesg, so whatever issue you're encountering on 12 doesn't seem to exist on 11.2. You might want to try using HEAD (like a snapshot that's post 1/30), since there have been a couple fixes to the em driver in the past couple days.
(In reply to kaan from comment #0) Do you still have this hardware? I'd like to see pciconf -lv for the em devices, and have you retest on 12.2-RELEASE or 13.0-RELEASE.
Yes, we still use this hardware, I updated it to 11.4 and I plan to migrate to version 13 but because this is a rather critical network node, we will carry out migration in the summer. This is the pciconf -lv output for all devices: hostb0@pci0:0:0:0: class=0x060000 card=0x0f318086 chip=0x0f008086 rev=0x0e hdr=0x00 vendor = 'Intel Corporation' device = 'Atom Processor Z36xxx/Z37xxx Series SoC Transaction Register' class = bridge subclass = HOST-PCI vgapci0@pci0:0:2:0: class=0x030000 card=0x0f318086 chip=0x0f318086 rev=0x0e hdr=0x00 vendor = 'Intel Corporation' device = 'Atom Processor Z36xxx/Z37xxx Series Graphics & Display' class = display subclass = VGA ahci0@pci0:0:19:0: class=0x010601 card=0x0f238086 chip=0x0f238086 rev=0x0e hdr=0x00 vendor = 'Intel Corporation' device = 'Atom Processor E3800 Series SATA AHCI Controller' class = mass storage subclass = SATA xhci0@pci0:0:20:0: class=0x0c0330 card=0x0f358086 chip=0x0f358086 rev=0x0e hdr=0x00 vendor = 'Intel Corporation' device = 'Atom Processor Z36xxx/Z37xxx, Celeron N2000 Series USB xHCI' class = serial bus subclass = USB none0@pci0:0:26:0: class=0x108000 card=0x0f188086 chip=0x0f188086 rev=0x0e hdr=0x00 vendor = 'Intel Corporation' device = 'Atom Processor Z36xxx/Z37xxx Series Trusted Execution Engine' class = encrypt/decrypt hdac0@pci0:0:27:0: class=0x040300 card=0x0f048086 chip=0x0f048086 rev=0x0e hdr=0x00 vendor = 'Intel Corporation' device = 'Atom Processor Z36xxx/Z37xxx Series High Definition Audio Cont roller' class = multimedia subclass = HDA pcib1@pci0:0:28:0: class=0x060400 card=0x0f488086 chip=0x0f488086 rev=0x0e hdr=0x01 vendor = 'Intel Corporation' device = 'Atom Processor E3800 Series PCI Express Root Port 1' class = bridge subclass = PCI-PCI pcib2@pci0:0:28:1: class=0x060400 card=0x0f4a8086 chip=0x0f4a8086 rev=0x0e hdr=0x01 vendor = 'Intel Corporation' device = 'Atom Processor E3800 Series PCI Express Root Port 2' class = bridge subclass = PCI-PCI pcib3@pci0:0:28:2: class=0x060400 card=0x0f4c8086 chip=0x0f4c8086 rev=0x0e hdr=0x01 vendor = 'Intel Corporation' device = 'Atom Processor E3800 Series PCI Express Root Port 3' class = bridge subclass = PCI-PCI pcib4@pci0:0:28:3: class=0x060400 card=0x0f4e8086 chip=0x0f4e8086 rev=0x0e hdr=0x01 vendor = 'Intel Corporation' device = 'Atom Processor E3800 Series PCI Express Root Port 4' class = bridge subclass = PCI-PCI ehci0@pci0:0:29:0: class=0x0c0320 card=0x0f348086 chip=0x0f348086 rev=0x0e hdr=0x00 vendor = 'Intel Corporation' device = 'Atom Processor Z36xxx/Z37xxx Series USB EHCI' class = serial bus subclass = USB isab0@pci0:0:31:0: class=0x060100 card=0x0f1c8086 chip=0x0f1c8086 rev=0x0e hdr=0x00 vendor = 'Intel Corporation' device = 'Atom Processor Z36xxx/Z37xxx Series Power Control Unit' class = bridge subclass = PCI-ISA none1@pci0:0:31:3: class=0x0c0500 card=0x0f128086 chip=0x0f128086 rev=0x0e hdr=0x00 vendor = 'Intel Corporation' device = 'Atom Processor E3800 Series SMBus Controller' class = serial bus subclass = SMBus em0@pci0:1:0:0: class=0x020000 card=0x6c401462 chip=0x150c8086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = '82583V Gigabit Network Connection' class = network subclass = ethernet em1@pci0:2:0:0: class=0x020000 card=0x6c401462 chip=0x150c8086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = '82583V Gigabit Network Connection' class = network subclass = ethernet em2@pci0:3:0:0: class=0x020000 card=0x6c401462 chip=0x150c8086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = '82583V Gigabit Network Connection' class = network subclass = ethernet em3@pci0:4:0:0: class=0x020000 card=0x6c401462 chip=0x150c8086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = '82583V Gigabit Network Connection' class = network subclass = ethernet
