https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236962 Bug ID: 236962 Summary: Realtek RTL8111/8168/8411 erratically drops network connection Product: Base System Version: 12.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: marcel@herrbischoff.com I have encountered this issue multiple times on at least two dedicated servers, one running 12.0-RELEASE and one 11.2-RELEASE. Both have identical Realtek ethernet controllers. "pciconf -lv" on 11.2 machine: re0@pci0:2:0:0: class=0x020000 card=0x78161462 chip=0x816810ec rev=0x06 hdr=0x00 vendor = 'Realtek Semiconductor Co., Ltd.' device = 'RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller' class = network subclass = ethernet "pciconf -lv" on 12.0 machine: re0@pci0:2:0:0: class=0x020000 card=0x78161462 chip=0x816810ec rev=0x06 hdr=0x00 vendor = 'Realtek Semiconductor Co., Ltd.' device = 'RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller' class = network subclass = ethernet The machine is not reachable because it drops the network connection repeatedly with the following output in "/var/log/messages": [...] Apr 2 10:29:01 <kern.crit> cloud kernel: [5054487] re0: watchdog timeout Apr 2 10:29:01 <kern.notice> cloud kernel: [5054487] re0: link state changed to DOWN Apr 2 10:29:04 <kern.notice> cloud kernel: [5054490] re0: link state changed to UP Apr 2 10:33:31 <kern.crit> cloud kernel: [5054757] re0: watchdog timeout Apr 2 10:33:31 <kern.notice> cloud kernel: [5054757] re0: link state changed to DOWN Apr 2 10:33:34 <kern.notice> cloud kernel: [5054760] re0: link state changed to UP Apr 2 10:38:01 <kern.crit> cloud kernel: [5055027] re0: watchdog timeout Apr 2 10:38:01 <kern.notice> cloud kernel: [5055027] re0: link state changed to DOWN Apr 2 10:38:04 <kern.notice> cloud kernel: [5055030] re0: link state changed to UP Apr 2 10:42:35 <kern.crit> cloud kernel: [5055301] re0: watchdog timeout Apr 2 10:42:35 <kern.notice> cloud kernel: [5055301] re0: link state changed to DOWN Apr 2 10:42:38 <kern.notice> cloud kernel: [5055304] re0: link state changed to UP [...] This repeats infinitely and renders the machine essentially unusable. There is no apparent pattern to this behavior like higher-than-usual load or bandwidth usage and both machines have no special configuration regarding network settings or the like, it's all out-of-the-box. -- You are receiving this mail because: You are the assignee for the bug.help
