Hello, Javier,
Thanks. I tried accordingly. I change the line in /boot/grub/grob.conf from
kernel /vmlinuz-2.6.12-1.1398_FC4smp ro root=LABEL=/ rhgb quiet
to
kernel /vmlinuz-2.6.12-1.1398_FC4smp ro root=LABEL=/ rhgb quiet selinux=0
. I then reboot the linux. I would assume it will disable SElinux
altogehter. The problem remains. I seems like it is not about SElinux.
Thanks!
Gray
