when debugging drivers using printk i've the problem that most often the msg passed to printk don't show up on the console since the machine crashed before. i also what to use my own ASSERT macros which halt the machine immediatly on an error. i could write some functions that write the debug string to the serial port but this is impractical since if've a cluster of pc and i can't connect them all to some serial lines for debugging. are there some functions which write directly into the graphic cards ram assuming that thy operate in console mode, no x-server running? or is ther any other way to for reliable debug prints. - 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/
