Hi all,
does anyone have a hint on what's happening here?
I keep running into panics when copying world from the USB stick i boot
from, to the internal SD-Card where I want to boot from next.
backtrace:
root@dreamplug:/ # panic: Lock vm object not exclusively locked @
/usr/devel/dre
amplug/sys/arm/arm/pmap.c:4474
