--- Comment #7 from Tino Engel <tino.en...@mail.de> --- I had the same problem about a year ago - unfortunately I have forgotten what workaround I used. Anyhow when I look at the source of /usr/ports/net/realtek-re-kmod/work/rtl_bsd_drv-d3a7a3d/if_re.c where the problem seems to happen: 7103 #if OS_VER < VERSION(4,9) 7104 /* Remove header from mbuf and pass it on. */ 7105 m_adj(m, sizeof(struct ether_header)); 7106 ether_input(ifp, eh, m); 7107 #else 7108 (*ifp->if_input)(ifp, m); 7109 #endif 7110 RE_LOCK(sc); >From the crash dump stacks, it seems to end up in line 7106, which is between #if OS_VER < VERSION(4,9) and #else see also Comment #4: #8 ether_input (ifp=<optimized out>, m=0xffff) at /usr/src/sys/net/if_ethersubr.c:849 That seems wrong to me for FreeBSD 13. See if_rereg.h: #define OS_VER __FreeBSD_version -- You are receiving this mail because: You are the assignee for the bug.
