with no patch and SMP enabled I have another kind of panics, like:

[...]
Starting cron.
panic: mutex pmap not owned at /usr/home/br/dev/head/sys/arm/arm/pmap-v6.c:4184
cpuid = 1
[...]

[...]

     media: Ethernet autoselect (100baseTX <full-duplex>)

     nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
