Problems with updatep2(nanobsd) on soekris 4801

[jkv]

Hi,

Im currently experiencing some unexpected problems on my nanobsd(freebsd 
7.0-release) running on a soekris 4801.
The system have been running good for some time, but yesterday i decided 
to update the system with a few more packages.
As described in the documentations i made a new image(using the same 
nanobsd conf file as i used at the initial setup) and tried to update 
partition 2 with the updatep2 script, but for some reason this causes my 
system to crash.

Any ideas?

Regards,
Johnny

(10.0.0.45 is the freebsd which i use for compiling the images)

nanobsd# nc 10.0.0.45 5555 | sh updatep2
