I though i would be a good user and report this one. I first noticed
this on my friend's box when i helped him install linux on a new PC.
It's a Athlob XP UMP box, with a VIA KT333 chipset (if i'm not
mistaken). Here is a cut output of dmesg (on 2.4.20). Hope it helps out.
I'm not suscribed so please CC me if you need anything.
