https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270163 Bug ID: 270163 Summary: Intel 82571EB quad port adapter causing ifconfig response delays when only one interface plugged in at boot Product: Base System Version: 13.1-STABLE Hardware: powerpc OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: tpearson@raptorengineering.com When using a 82571EB quad port Ethernet adapter under FreeBSD 13.1, I am observing a persistent and significant delay in ifconfig responses if the machine was booted without all four Ethernet ports connected and active. T= his delay shows up as ifconfig is attempting to gather media information and li= nk state, and lasts for ~50 seconds Once the device enters this state, it no longer detects link state changes = on Ethernet ports that have been connected after boot. Connecting a network c= able to the port continues to register link down, even though the card lights sh= ow activity on that port. Bad link state output: media: Ethernet autoselect status: no carrier Correct link state output: media: Ethernet autoselect (1000baseT <full-duplex>) status: active Even with all four ports connected, subsequent link state changes are not registered. I suspect there may be an issue communicating with the PHYs af= ter initial driver setup has completed. I am using CARP on these interfaces. Other Ethernet adapter models I have tested do not appear to exhibit this problem. Rarely (less than 1 in 100 chance), the system starts normally on its own a= nd all link state changes are reflected correctly until the next reboot. No abnormal messages appear in dmesg. The cards operate normally under Linux. --=20 You are receiving this mail because: You are the assignee for the bug.=
