I've recently upgraded a 5.4-STABLE box to 6.0-BETA2 (as of August 16th
or so), and since the upgrade, the machine has panicked every other day
or so. 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));

This is a box I'm able to try nearly anything on, so let me know what
else I can do/provide.
