(It was noticably faster with 2.3 kernels, btw. Now it spends a second or two apparently not noticing the APM event (though the BIOS is making the speaker beep), then syncing the disk, then maybe another pause, then maybe some more disk activity, then finally shutting down. 2.3 started the disk activity immediately and didn't pause. Perhaps 2.4.3 mm problems?) -- Jamie - 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/
