Sorry, this was a bad report.  Thought it might be a regression in the
preemption stuff, but still I should have provided more info than I
did.  Let me give what I can and you can let me know if there is
anything more I can provide.  I get a long string of panic info but no
core dump or drop into debugger.  Just a reboot.  I tried to look at the
address in the debugger and this is what I get:

(gdb) list *0xffffffff80351940
0xffffffff80351940 is in m_copym (/usr/src/sys/kern/uipc_mbuf.c:373).
368             MBUF_CHECKSLEEP(wait);
369             if (off == 0 && m->m_flags & M_PKTHDR)
370                     copyhdr = 1;
371             while (off > 0) {
372                     KASSERT(m != NULL, ("m_copym, offset > size of mbuf chain"));
373                     if (off < m->m_len)
374                             break;
375                     off -= m->m_len;
376                     m = m->m_next;
377             }

I think it goes off into lala land after that.  Here is the full panic.
