cedega 的 error=21 错误解决办法

1. Disable Prelinking after reboot

# vi /etc/sysconfig/prelink
PRELINKING=no
PRELINKING=-no-exec-shield

2. Unlink all prelinked files on running system

# /usr/sbin/prelink -ua

3. Disable Exec-Shield after reboot:

# vi /etc/sysctl.conf
kernel.exec-shield = 0
kernel.exec-shield-randomize= 0
vm.legacy_va_layout = 1

4. Disable Exec-Shield in running kernel

# echo 0 > /proc/sys/kernel/exec-shield
# echo 0 > /proc/sys/kernel/exec-shield-randomize
# echo 1 > /proc/sys/vm/legacy_va_layout

如果还不行，就在挂载 fat 分区的选项里添加 exec。
