Some more info. If cstrike/sound/weapons is moved (ex.
renamed) the
server loads fine.

I've done an RTFS and seen that linux_getdents and
linux_getdents64
use different data structures. Linux_base-fc4 uses
linux_getdents64
here and succeeds while linux_base-fc6 quite the opposite.

The directory cstrike/sound/weapons is the largest (165
files), other
directories are way smaller. Seems that linux_getdents() get
something
like buffer overflow or else.

BTW, why does linux_base-fc6 uses linux_getdents everywhere
while
linux_base-fc4 uses linux_getdents64?
