At least on 760MPX chipset, when Athlon is pushed into powersaving mode (disconnected from PCI bus) great deal of graphical distortions are introduced into bttv -based card's picture. I've dealt with this by rmmod:ing amd76x_pm -module (this action disables powersaving mode), but some sane API for disabling these disturbancies would be much better. -- Psi -- <http://www.iki.fi/pasi.savolainen> - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
