I'm not sure, but in the case of FIBRE, the behavior around link status may be different from TP. As a workaround, following patch to force polling linkstat. Will this solve the problem? cvs -q diff -U8 -a -p if_aq.c Index: if_aq.c =================================================================== RCS file: /cvsroot/src/sys/dev/pci/if_aq.c,v retrieving revision 1.11 diff -U 8 -a -p -r1.11 if_aq.c --- if_aq.c 15 Feb 2020 12:20:35 -0000 1.11 +++ if_aq.c 22 Apr 2020 08:02:02 -0000 @@ -1301,16 +1301,21 @@ aq_attach(device_t parent, device_t self sc->sc_use_txrx_independent_intr = false; sc->sc_poll_linkstat = true; sc->sc_msix = true; } else { /* giving up using MSI-X */ sc->sc_msix = false; } +#define FORCE_POLL_LINKSTAT +#ifdef FORCE_POLL_LINKSTAT + sc->sc_poll_linkstat = true; +#endif + aprint_debug_dev(sc->sc_dev, "ncpu=%d, pci_msix_count=%d."
