Compiled 2.6.14, seeing strange things...
Hi.
I compiled 2.6.14 since I like having the framebuffer support and the
Debian pre-packaged kernels don't have it in with 2.6.14, as well as
headaches with yaboo (or whatever the heck it is) initrd generator.
So I built it without initrd, and with ext3 compiled in.
When I enabled preemption, I noticed that the system (2.8GHz P4
laptop) became very jerky and pulling the mouse across the screen was
an exercise in patience.
I recompiled without preemption, and while mouse/keyboard response has
improved almost to Debian-precompiled quality, now something else is
happening:

17% kjournald? Now, true, it's running an ftp, but it's only 300kBps.
I have done full 100Mbps ethernet dumps that didn't blink an eye.
Not only that, but every 5 seconds, the commit time for the ext3
journal, there is a noticable 1/2 second pause in keyboard/software
response. This has not happened at all with the Debian compiled
kernels.
If someone wants to discuss this, I would love to share kernel build
config files and such to try and find where this is "going wrong".
