I'm not aware of any stack-specific issues with Reiser, only XFS (though it 
appears JFS has issues too).

If its a Red Hat or Fedora Core 2.6 kernel, installed from one of Red Hat's 
kernel rpms, its 4kstacks. Otherwise, you likely would have had to enable 
4kstacks in a kernel of your own building (though I seem to recall Gentoo 
possibly defaulting to 4kstacks if you're using genkernel).

Sounds like Reiser just plain sucks for large files like those associated with 
HDTV, but it isn't a kernel stack size issue. I'd switch to a different file 
system myself.
