Bug#273638: Kernel 2.6.8-1-686 extremly slow
Package: kernel-image-2.6.8-1-686
Version: 2.6.8-3
Hi,
it seems that the 2.6.8-3 kernel image reacts very slow. After upgrading my
laptop (Sony VAIO PCG-F709) to the latest testing version of the 2.6 kernel
and starting KDE, I can watch every stroke on the keyboard appear on the
screen.
Here is some information:

Running top I can see, that the system always has a load around 2.5 on my
Pentium III, the X-Server always needs 30% of CPU time:

I know that my memory is almost full, but even when the system has been booted
the machine reacts still slow.
I didn't have that behaviour wit the 2.6.8-2 kernel image.
Regards,
Michael
