I'm sorry that I changed the status to "Confirmed" - I didn't think that I had such user rights. But, maybe it should stay so, because I can definitely confirm, that:
1) this issue does relate to the network activity, and only to the outgoing one;
2) it goes away compeletely with acpi=off, which in its turn may break something else (in my case, Asterisk server)
3) it still exists in Karmic, 2.6.31-14
