Hi, Every once in a while, my system gets unbelievable slow. So slow that I almost can't do anything anymore. This happens only once in a few months. I think it has to do with sound, because when I start using sound, it happens. "top" gives me then about 90% idle time, and "top" is using this 10% then. This already happens quite a while. I already had this with a 2.2.x kernel and I just had it with the 2.4.2 kernel. Could you tell me what I can do to give you more information ? Do you think it could be in this module ? I use the es1370 driver as a loadable module that gets loaded when asked for it. I always use standard distribution installation. Now I have RH7.1 With kind regards, Edwin. info : [root@CC90001-A /root]# cat /proc/pci PCI devices found: Bus 0, device 0, function 0: Host bridge: Acer Laboratories Inc. [ALi] M1541 (rev 4).
