hi,
i play with the sde990 on my stordis, remotely... for now, i start everything 
by hand, and i face a strange issue:
first i start run_switchd.sh, then i start freerouter, then i start 
bf_forwarder... at this point, everything works
as expected... but as soon i restart bf_forwarder while keeping bfswd and 
freerouter running, bfforwarder cannot
the asic anymore with the below very strange message... nevertheless to say 
that the mentioned file is in place,
unchanged, and after restarting bfswd, it does not complain about it 
anymore...
my question is, if you could spin up a similar test on a wedge to rule out if 
it's the apsn's bsp of the sde990?
thanks,
cs
