'Unknown HZ value' warning from top/ps

It is a 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.

--param ggc-min-expand=0 --param ggc-min-heapsize=<max_ram_gcc_is_allowed_to_take>'

I chose 32768. Thanks to 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).
