https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270163 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: firstname.lastname@example.org 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. This delay shows up as ifconfig is attempting to gather media information and link 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 cable to the port continues to register link down, even though the card lights show 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 after 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 and all link state changes are reflected correctly until the next reboot. No abnormal messages appear in dmesg. The cards operate normally under Linux. -- You are receiving this mail because: You are the assignee for the bug.
