[Openswan Users] Problem with openswan in embedded system

[Panagiotis Tamtamis]

Actually is not really an embedded system. You can say more that it is
a customized pc.
So actually we don't really have resource problems

I just recompiled the kernel with more debug information hoping to get more
info about the errors.

Its a pc based kernel so it has MMU

And I will surely provide more info if I find anything more!
