Ata host bus error

Sziasztok,

Van egy alaplapom ICH7 chipset-tel. Az utóbbi időben a log tele van a lenti üzenetekkel. A vezérlőn lóg egy 16GB-os SSD (ezen van a rendszer), egy WD 500GB disk és egy DVD író. Akkor kezdenek jönni a lenti hibák, amikor megnő a terhelés a diszken. KDM login után ~1 percre befagy a gép míg kínlódik a diszkel, majd a végén leesik a sebesség UDMA/33-ra. A kérdés, hogy diszk hibáról van-e szó, vagy valóban a chipset/alaplap döglődik (host bus error). A diszk ~2 hónapos kora után már jöttek a lenti hibák.
