Hello, Adrian. You wrote 27 =E0=E2=E3=F3=F1=F2=E0 2012 =E3., 2:26:08: AC> If you manage to get an 11n NIC for your soekris and you can bring up I have one :) And it works great now. But system hangs up under 802.11n load (I suspect overheat, really). And 40Mbit wire-2-wire transfer with lots of stream (torrents) kills any wifi transfer, mostly due to high interrupt rate on old PCI-based 1G Intel card (it shows about 4K interrupts per second, with interrupt moderation enabled!). But only System -> em0 transfer (Download from server's point of view). I'm investigating this now and post all my results to current@ and net@.

I'm not sure, that Geode has hwpmc at all. I found this: http://www.freebsd.org/cgi/query-pr.cgi?pr=3D156540 It looks, like there is no hwpmc for this old embedded CPU. --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
