====== Known issues ======
===== 'Unknown HZ value' warning from top/ps =====
It is a [[http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=460331|procps bug]]. This warning doesn't break anything.

===== emerge pygtk results in 100% cpu usage by gcc on gtk.c for inadequate amount on time (tens of hours) =====
This is a lack of optimization in gcc due to what it needs a lot of RAM (400mb on my amd64 desktop) in order to compile gtk.c file. Build pygtk without ''-O'' optimizations.

===== gcc eats ram like crazy during package compilation =====
In order to keed down gcc appetite add the following to CFLAGS in make.conf.
<code>--param ggc-min-expand=0 --param ggc-min-heapsize=<max_ram_gcc_is_allowed_to_take>'</code>
I chose 32768. Thanks to [[http://www.internettablettalk.com/forums/showpost.php?p=220028|fanoush]] for this hint.

===== Starting KDE 4 crashes on X.org 7.2 =====
X.org 7.2 (server 1.3.0) crashes if we try to start KDE 4. This problem does not occur with X.org 7.4 (server 1.5.3)

===== Lots of devices missing =====
Use <=sys-fs/udev-141 (newer versions do not work with ancient 2.6.21 currently present on n8x0).
