My home server lost connection on em0 this night again. It was persistent problem some times ago, but with version 7.2.3 it is first time, but with worse symptoms. It looks like undetected hardware hang-up: no packets could be sent or received, and no any output in dmesg or log files. Interface up/down with ifconfig and cable unplugging doesn't help: ifaces sees all these changes, but no packets could be sent/received anyway. I was forced to reboot server to make it work again. IT is rather old 8-STABLE (Oct 2011), but it sems, that last change in e1000 for 8-STABLE was r223675, in Jun 2011, so it is "fresh" sources (I don't believe, that r229147 is related). Output of `sysctl dev.em' when card is not working (but after some up/down events) is attached. NIC is: em0: port 0xd880-0xd89f mem 0x= fea40000-0xfea5ffff,0xfea7a000-0xfea7afff irq 20 at device 25.0 on pci0 em0: Using an MSI interrupt em0: [FILTER] em0: Ethernet address: 00:1e:8c:75:03:0d em0@pci0:0:25:0: class=3D0x020000 card=3D0x82681043 chip=3D0x10bd808= 6 rev=3D0x02 hdr=3D0x00 vendor =3D 'Intel Corporation' device =3D 'Intel 82566DM Gigabit Ethernet Adapter (82566DM)' class =3D network subclass =3D ethernet --=20 // Black Lion AKA Lev Serebryakov ------------5C7120A21F19B1B Content-Type: text/plain; name="sysctl-dev-em.txt" Content-transfer-encoding: base64 Content-Disposition: attachment; filename="sysctl-dev-em.txt" ZGV2LmVtLjAuJWRlc2M6IEludGVsKFIpIFBSTy8xMDAwIE5ldHdvcmsgQ29ubmVjdGlvbiA3 LjIuMwpkZXYuZW0uMC4lZHJpdmVyOiBlbQpkZXYuZW0uMC4lbG9jYXRpb246IHNsb3Q9MjUg ZnVuY3Rpb249MCBoYW5kbGU9XF9TQl8uUENJMC5HQkVDCmRldi5lbS4wLiVwbnBpbmZvOiB2 ZW5kb3I9MHg4MDg2IGRldmljZT0weDEwYmQgc3VidmVuZG9yPTB4MTA0MyBzdWJkZXZpY2U9 MHg4MjY4IGNsYXNzPTB4MDIwMDAwCmRldi5lbS4wLiVwYXJlbnQ6IHBjaTAKZGV2LmVtLjAu bnZtOiAtMQpkZXYuZW0uMC5kZWJ1ZzogLTEKZGV2LmVtLjAucnhfaW50X2RlbGF5OiAwCmRl di5lbS4wLnR4X2ludF9kZWxheTogNjYKZGV2LmVtLjAucnhfYWJzX2ludF9kZWxheTogNjYK ZGV2LmVtLjAudHhfYWJzX2ludF9kZWxheTogNjYKZGV2LmVtLjAucnhfcHJvY2Vzc2luZ19s aW1pdDogMTAwCmRldi5lbS4wLmZsb3dfY29udHJvbDogMwpkZXYuZW0uMC5lZWVfY29udHJv bDogMApkZXYuZW0uMC5saW5rX2lycTogMApkZXYuZW0uMC5tYnVmX2FsbG9jX2ZhaWw6IDAK ZGV2LmVtLjAuY2x1c3Rlcl9hbGxvY19mYWlsOiAwCmRldi5lbS4wLmRyb3BwZWQ6IDAKZGV2 LmVtLjAudHhfZG1hX2ZhaWw6IDAKZGV2LmVtLjAucnhfb3ZlcnJ1bnM6IDc3NDIKZGV2LmVt LjAud2F0Y2hkb2dfdGltZW91dHM6IDAKZGV2LmVtLjAuZGV2aWNlX2NvbnRyb2w6IDE0Nzc0 NDQxNjAKZGV2LmVtLjAucnhfY29udHJvbDogNjcxNDE2MzQKZGV2LmVtLjAuZmNfaGlnaF93 YXRlcjogODE5MgpkZXYuZW0uMC5mY19sb3dfd2F0ZXI6IDY2OTIKZGV2LmVtLjAucXVldWUw LnR4ZF9oZWFkOiAxNTgKZGV2LmVtLjAucXVldWUwLnR4ZF90YWlsOiAxMjUKZGV2LmVtLjAu cXVldWUwLnR4X2lycTogMApkZXYuZW0uMC5xdWV1ZTAubm9fZGVzY19hdmFpbDogMApkZXYu ZW0uMC5xdWV1ZTAucnhkX2hlYWQ6IDM2MjQKZGV2LmVtLjAucXVldWUwLnJ4ZF90YWlsOiAz NjIzCmRldi5lbS4wLnF1ZXVlMC5yeF9pcnE6IDAKZGV2LmVtLjAubWFjX3N0YXRzLmV4Y2Vz c19jb2xsOiAwCmRldi5lbS4wLm1hY19zdGF0cy5zaW5nbGVfY29sbDogMApkZXYuZW0uMC5t YWNfc3RhdHMubXVsdGlwbGVfY29sbDogMApkZXYuZW0uMC5tYWNfc3RhdHMubGF0ZV9jb2xs OiAwCmRldi5lbS4wLm1hY19zdGF0cy5jb2xsaXNpb25fY291bnQ6IDAKZGV2LmVtLjAubWFj X3N0YXRzLnN5bWJvbF9lcnJvcnM6IDAKZGV2LmVtLjAubWFjX3N0YXRzLnNlcXVlbmNlX2Vy cm9yczogMApkZXYuZW0uMC5tYWNfc3RhdHMuZGVmZXJfY291bnQ6IDM0MDQyNzEKZGV2LmVt LjAubWFjX3N0YXRzLm1pc3NlZF9wYWNrZXRzOiAxNDM2MTYKZGV2LmVtLjAubWFjX3N0YXRz LnJlY3Zfbm9fYnVmZjogMApkZXYuZW0uMC5tYWNfc3RhdHMucmVjdl91bmRlcnNpemU6IDAK ZGV2LmVtLjAubWFjX3N0YXRzLnJlY3ZfZnJhZ21lbnRlZDogNzMKZGV2LmVtLjAubWFjX3N0 YXRzLnJlY3Zfb3ZlcnNpemU6IDAKZGV2LmVtLjAubWFjX3N0YXRzLnJlY3ZfamFiYmVyOiAw CmRldi5lbS4wLm1hY19zdGF0cy5yZWN2X2VycnM6IDE1NDUKZGV2LmVtLjAubWFjX3N0YXRz LmNyY19lcnJzOiAxNjEwCmRldi5lbS4wLm1hY19zdGF0cy5hbGlnbm1lbnRfZXJyczogMApk ZXYuZW0uMC5tYWNfc3RhdHMuY29sbF9leHRfZXJyczogNgpkZXYuZW0uMC5tYWNfc3RhdHMu eG9uX3JlY3ZkOiAzNTYwNjI0CmRldi5lbS4wLm1hY19zdGF0cy54b25fdHhkOiAwCmRldi5l bS4wLm1hY19zdGF0cy54b2ZmX3JlY3ZkOiA0MzU0MTMyOQpkZXYuZW0uMC5tYWNfc3RhdHMu eG9mZl90eGQ6IDAKZGV2LmVtLjAubWFjX3N0YXRzLnRvdGFsX3BrdHNfcmVjdmQ6IDEzOTM2 NDUyMzgKZGV2LmVtLjAubWFjX3N0YXRzLmdvb2RfcGt0c19yZWN2ZDogMTM0NjQ2NDQ5OQpk ZXYuZW0uMC5tYWNfc3RhdHMuYmNhc3RfcGt0c19yZWN2ZDogMzA3NDQKZGV2LmVtLjAubWFj X3N0YXRzLm1jYXN0X3BrdHNfcmVjdmQ6IDg3NjMKZGV2LmVtLjAubWFjX3N0YXRzLnJ4X2Zy YW1lc182NDogMApkZXYuZW0uMC5tYWNfc3RhdHMucnhfZnJhbWVzXzY1XzEyNzogMApkZXYu ZW0uMC5tYWNfc3RhdHMucnhfZnJhbWVzXzEyOF8yNTU6IDAKZGV2LmVtLjAubWFjX3N0YXRz LnJ4X2ZyYW1lc18yNTZfNTExOiAwCmRldi5lbS4wLm1hY19zdGF0cy5yeF9mcmFtZXNfNTEy XzEwMjM6IDAKZGV2LmVtLjAubWFjX3N0YXRzLnJ4X2ZyYW1lc18xMDI0XzE1MjI6IDAKZGV2 LmVtLjAubWFjX3N0YXRzLmdvb2Rfb2N0ZXRzX3JlY3ZkOiAxNTc3NzEyOTY1MzQKZGV2LmVt LjAubWFjX3N0YXRzLmdvb2Rfb2N0ZXRzX3R4ZDogMzEwNTc5OTM3OTQwNApkZXYuZW0uMC5t YWNfc3RhdHMudG90YWxfcGt0c190eGQ6IDIyODk5MTQyNzgKZGV2LmVtLjAubWFjX3N0YXRz Lmdvb2RfcGt0c190eGQ6IDIyODk5MTQyNzgKZGV2LmVtLjAubWFjX3N0YXRzLmJjYXN0X3Br dHNfdHhkOiA0Nzc2CmRldi5lbS4wLm1hY19zdGF0cy5tY2FzdF9wa3RzX3R4ZDogMTAxNzkw CmRldi5lbS4wLm1hY19zdGF0cy50eF9mcmFtZXNfNjQ6IDAKZGV2LmVtLjAubWFjX3N0YXRz LnR4X2ZyYW1lc182NV8xMjc6IDAKZGV2LmVtLjAubWFjX3N0YXRzLnR4X2ZyYW1lc18xMjhf MjU1OiAwCmRldi5lbS4wLm1hY19zdGF0cy50eF9mcmFtZXNfMjU2XzUxMTogMApkZXYuZW0u MC5tYWNfc3RhdHMudHhfZnJhbWVzXzUxMl8xMDIzOiAwCmRldi5lbS4wLm1hY19zdGF0cy50 eF9mcmFtZXNfMTAyNF8xNTIyOiAwCmRldi5lbS4wLm1hY19zdGF0cy50c29fdHhkOiA2NTIy NDA3ODkKZGV2LmVtLjAubWFjX3N0YXRzLnRzb19jdHhfZmFpbDogMApkZXYuZW0uMC5pbnRl cnJ1cHRzLmFzc2VydHM6IDEzNzUwNDEwMzEKZGV2LmVtLjAuaW50ZXJydXB0cy5yeF9wa3Rf dGltZXI6IDAKZGV2LmVtLjAuaW50ZXJydXB0cy5yeF9hYnNfdGltZXI6IDAKZGV2LmVtLjAu aW50ZXJydXB0cy50eF9wa3RfdGltZXI6IDAKZGV2LmVtLjAuaW50ZXJydXB0cy50eF9hYnNf dGltZXI6IDAKZGV2LmVtLjAuaW50ZXJydXB0cy50eF9xdWV1ZV9lbXB0eTogMApkZXYuZW0u MC5pbnRlcnJ1cHRzLnR4X3F1ZXVlX21pbl90aHJlc2g6IDAKZGV2LmVtLjAuaW50ZXJydXB0 cy5yeF9kZXNjX21pbl90aHJlc2g6IDAKZGV2LmVtLjAuaW50ZXJydXB0cy5yeF9vdmVycnVu OiAwCmRldi5lbS4wLndha2U6IDAK ------------5C7120A21F19B1B--
