I can reproduce this behaviour with an UML kernel linux-v2.6.36-rc7-153-
g0acc1b2 if I start the UML guest (an almost stable Gentoo) and then run from
the host system (Gentoo too) this:
§> wget http://n22_uml/phpsysinfo/
- where n22_uml is the guest and the side is an PHP application :
http://phpsysinfo.sourceforge.net/
It is not related to PHP and/or apache b/c phpmyadmin works fine. I argue that
sth is wrong with the reading of /proc and/sys files b/c that is the main part
of phpsysinfo.
Furthermore it is a regression b/c 2.6.35 UML kernel works fine.
Here's the kernel info :
