    Hi,

    I keep getting this panic on RELENG_6 when downloading data from a
    net/mpd link (GRE).

    This GDB was configured as "i386-marcel-freebsd".
    #0 doadump () at pcpu.h:165
    165 pcpu.h: No such file or directory.
             in pcpu.h

    #3 0xc066e296 in sbappendstream_locked (sb=0xc27f2050, m=0xc222b600)

    #10 0xc07dc2dc in fork_trampoline () at /usr/src/sys/i386/i386/exception.s:208

    I get a similar panic on RELENG_5 ("panic: sbappend") but I don't have
    a traceback right now.
