I've made the following change:
Index: sys/dev/bce/if_bce.c
===================================================================
- --- sys/dev/bce/if_bce.c (revision 233291)
+++ sys/dev/bce/if_bce.c (working copy)
@@ -7678,6 +7678,9 @@ bce_intr(void *xsc)
BCE_LOCK(sc);
+ if ((ifp->if_drv_flags & IFF_DRV_RUNNING) != IFF_DRV_RUNNING)
+ BCE_PRINTF("Got interrupt without IFF_DRV_RUNNING!\n");
+
DBRUN(sc->interrupts_generated++);
/* Synchnorize before we read from interface's status block */
Should we run with that and see if we can catch something?
Cheers,
