If yes and > you reproduce DMA error easily could you please show me the full dmesg? When it occurs, it is a fatal DMA error, and this streams on the console until reboot. In order to get the card to work again (with either bwn or ndis), I need to power-cycle the laptop. When it occurs again, I will get you the details and the full dmesg. Do you want a verbose dmesg, or a standard one? Joe -- Joe Marcus Clarke FreeBSD GNOME Team :: gnome@FreeBSD.org FreeNode / #freebsd-gnome http://www.FreeBSD.org/gnome
