Hi all,

I recently updated my dell Inspirion 8100's software after I found to
my suprise I could no longer play video fast enough to watch. I did a
kernel upgrade from 2.6.24 to 2.6.28, with a number of
reconfigurations, including moving from madwifi to in-kernel ath5k.
Also updated nvidia-drivers to go along with the new system.

Now my system is extremely sluggish. It updates the screen very slowly
in X and CPU performance is noticably slower without X running too.
WiFi speed is dismal.

I tried to remove all cruft and extras from the kernel, but I haven't
managed to improve matters yet. Since it now takes hours to update the
system, I was hoping someone might have and idea as to what the cause
of the slowdown might be.

Sound Familiar? Any guesses?

Good thought! I didn't have it on though. Not particularly useful on
a laptop.

I fixed it though; it ended up being the BIOS. An upgrade from 8 to
15 and it's like a new computer. Yay!

Thanks for the response.

I have been using 2.6.23 kernel for a while for the same reason. I'm
going to check my config now.
