Re: Increased CPU usage after upgrading to 2.6.21

Hi!
I recently upgraded from 2.6.19, and found the following issues:
1. 2.6.20 crashed and ran terribly on my system.
2. 2.6.21 runs on my system, but has a few issues: First, I noticed
that in 2.6.19 when my system was idle, Gkrellm would show my CPU
usage as 0%. In 2.6.21, when my system is idle, Gkrellm shows my
cpu usage as anything between 1 and 3%.
Second, I noticed that X sometimes crashes on resume (i.e. when I
wake my computer up after suspending to ram). Again, this happens
only *sometimes*, and is not consistently reproducible. I had no
issues with 2.6.19 (which I used for a long time).
3. For 2.6.22.1: The CPU usage issue is the same as above. I only
tested the kernel for a brief period of time (minutes), during
which I experienced no crash.
If you have any idea why my CPU usage is reported higher, please let me
know. I've attached the config files of both my kernels.
About the random crash: I'm not sure how to give you more info on it,
since I can't consistently reproduce it. Would you have any suggestions
on what I should do to trace the problem down?
Well, try suspend 50 times in a row to make it reproducible? Then try
unloading modules...
