You can Google for b43 & DMA errors. Simply try "pio" option for b43 module. Or switch to newer kernel, which will pick up pio for you after first DMA error. -- Rafał _______________________________________________ b43-dev mailing list [email protected] http://lists.infradead.org/mailman/listinfo/b43-dev
