https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=209682 --- Comment #12 from Dave Baukus <daveb@spectralogic.com> --- Back in March, 2018, I added hselasky's patch to our 11.1 base. I and have not seen this issues since. I did not add the patch to our 11.0 release; this bug reared its head in our 11.0 based release stream. I do know what triggers this event; I can not reproduce at will, but its seems that Hans Petter's patch is worthy. #6 0xffffffff8081908c in trap (frame=0xfffffe07c4ff37b0) at sys/amd64/amd64/trap.c:442 #7 0xffffffff807fd341 in calltrap () at sys/amd64/amd64/exception.S:236 #8 0xffffffff80625e64 in arptimer (arg=<value optimized out>) at sys/netinet/if_ether.c:265 #9 0xffffffff8050dd0a in softclock_call_cc (c=<value optimized out>, cc=<value optimized out>, direct=<value optimized out>) Again the ifp from lle->lle_tbl->llt_ifp is invalid: p *$lle->lle_tbl $4 = { llt_link = { sle_next = 0x0 }, llt_af = 0, llt_hsize = 0, lle_head = 0xfffff800286a6000, llt_ifp = 0x2, llt_lookup = 0xc1, llt_alloc_entry = 0, llt_delete_entry = 0x9, llt_prefix_free = 0xc0, llt_dump_entry = 0x1667, llt_hash = 0, llt_match_prefix = 0x1d97, llt_free_entry = 0x1a667b, llt_foreach_entry = 0x1, llt_link_entry = 0, llt_unlink_entry = 0, llt_fill_sa_entry = 0, llt_free_tbl = 0 } -- You are receiving this mail because: You are the assignee for the bug.
