I'm using APM && apmd, but it seems it does nothing. Now I'll test without apm module && apmd unloaded. Well, there's a strange thing: I have two drives: /dev/hda on /boot, /dev/hdc on / If i do hdparm -Y /dev/hda, without apm loaded, hda stops, i can't awake it. hdc remains working. Now, if i do hdparm -Y /dev/hdc i can sleep && awake hdc. But sometimes, when hda is working (or not) and with/without apm loaded the system stops, and hdc doesn't awake. I'm getting crazy.
Now when I try to mount the ide cdrom, mount keeps hanged, too.

I didn't know, i just read the hdparm manual, which doesn't says that. > - 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/
