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?
