So, after slowly eliminating possible causes, I came to (uncertain)
conclusion that f14 kernel does not like my network card (i.e. unless I
missed something, the only time I wasn't able to reproduce this yet is
without network cable plugged in). It also seems the freezes have got a
lot less frequent (but that might be purely coincidental).

Kernel:
kernel-2.6.35.4-28.fc14.i686

Network card:
06:01.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX
(rev 02)
