Actually 4k stacks are not the default.  Well in Fedora Core 2 and one 
of the 2.6 version (2.6.5 maybe?) it was not only the default, but it 
wasn't even an option IIRC.  In the 2.6.6 and 2.6.7 kernels 4k stacks 
are the option, 8k stacks are still the default at least when doing a 
make oldconfig on a .config that does not have a CONFIG_4KSTACKS line.

In my case I had to use 2.6.7 because I have a pcHDTV card and for some 
reason I couldn't get the pcHDTV patches to work with the Fedora kernel 
or even the vanilla 2.6.6 kernel (I have forgotten the exact problem, it 
was a couple of months ago).  So I rolled my own.  I even included the 
latest kraxel v4l2 patches to 2.6.7.  If you would like to see some 
information (not a complete HOWTO however) on what I did you can go to 
http://thegeorges.us/mythtv/ .

Next system upgrade I will try out kernel with latest nVidia 
(I'm still at 6106) and latest ivtv (I'm still at 99e).  I may have some 
time to mess with it this weekend while my wife is at work.

I will probably be sticking with 8k stacks for now.  Using the XFS 
filesystem (which I do) there is a small but real chance that if your 
filesystem fills up (and I have filled mine up a couple of times before 
I noticed) you may get a kernel oops.  For more info see
