I have the same behavior (i.e. it needs to be idle) except that it
lasts sometimes more than 5 minutes. I will try to start skype with a
"strace -tt -T -o strace.log slype" to see what gets printed just
before the system blocks. Feel free to do the same.

Blocking call will probably be revealed by:

grep -v "\<0\." strace.log

Very interesting. You don't have an Intel nor a Dell machine. At least
that rules out some common characteristics.
