ok, i have bisected it down but the result made no sense, so i
double-checked it and noticed that the .config mutated during the test.
the diff below is the diff between the 'good' and 'bad' .config, with
this notable detail:

so i disabled CONFIG_SECURITY_SMACK, and viola, just 2 hours of hard
work later networking works on my testbox again :-/
And we have this 1 day old commit:
commit e114e473771c848c3cfec05f0123e70f1cdbdc99
Author: Casey Schaufler <[EMAIL PROTECTED]>

Smack: Simplified Mandatory Access Control Kernel
that adds SMACK.
So unlike some other security modules like SELINUX, enabling SMACK
breaks un-aware userspace and breaks TCP networking?
I dont think that's expected behavior - and i'd definitely like to
enable SMACK in automated tests to check for regressions, etc.
