0x400 is a DMA ring descriptor error. That means the device is unable to read from main memory. It almost certainly is your BIOS corrupting the some PCI DMA settings when power sources are switched. You could try booting with noacpi or something like that. Maybe you could also play around with your BIOS settings. A BIOS update, if available, would also be a good thing to try. -- Greetings, Michael. _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
