Subjectbugreport : system unacceptably slow.
Date
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.
