I'm listening to a big .wav playing right now on my genuine SB16, while my Quantum hard disk is nattering away with DMA to my emacs (and wavplay). If I leave the room for a while the APM BIOS will shut down everything including spinning down the disk. The audio will stop because it's wavplay not a CD player ;-) Then I'll come back, hit shift and everything will come back. I don't expect any lockups. However, I have in the past had lockups related to DMA, with kernels 2.1.x only. They only happen if I don't do hdparm -X34 early on, and they take a few days to arise (usually). I don't need to use floppy or sound to get those lockups. These days, I am happy with my (touch wood) reliable and fast VP2-based board. So there. -- Jamie - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu Please read the FAQ at http://www.tux.org/lkml/faq.html | ||||||||||||
