I can't seem to find what might be triggering it, but mentions (m_tag_locate +0x38 cmpl ...) in the panic (and looking for the instruction pointer in nm -n kernel | grep points to the same thing). Digging around, I found these files with related matches: sys/dev/firewire/if_fwip.c: mtag = m_tag_locate(m, MTAG_FIREWIRE, MTAG_FIREWIRE_HWADDR, 0); sys/dev/usb/udbp.c: if ((ptag = (struct ng_tag_prio *)m_tag_locate(m, NGM_GENERIC_COOKIE, sys/kern/uipc_mbuf2.c:m_tag_locate(struct mbuf *m, u_int32_t cookie, int type, struct m_tag *t) sys/kern/uipc_mbuf2.c: KASSERT(m, ("m_tag_locate: null mbuf")); sys/net/if_fwsubr.c: mtag = m_tag_locate(m, MTAG_FIREWIRE, MTAG_FIREWIRE_HWADDR, NULL); sys/net/if_fwsubr.c: mtag = m_tag_locate(m, MTAG_FIREWIRE, MTAG_FIREWIRE_SENDER_EUID, 0); sys/sys/mbuf.h:struct m_tag *m_tag_locate(struct mbuf *, u_int32_t, int, struct m_tag *); sys/sys/mbuf.h: NULL : m_tag_locate(m, MTAG_ABI_COMPAT, type, start)); uname: FreeBSD hostname 6.0-BETA2 FreeBSD 6.0-BETA2 #1: Tue Aug 16 19:40:35 CDT 2005 root@hostname:/usr/obj/usr/src/sys/GENERIC i386 This is a box I'm able to try nearly anything on, so let me know what else I can do/provide.
