在笔记本Dell XPS-13上安装的Fedora 24，每次关机都会卡住，有时候等很久会自动关机，有时候着急就直接强制关机了。之前看到一些workaround是把wifi关掉，因为在关机时候有个下面的错误提示。但是我关掉还是卡住。
brcmf_cfg80211_reg_notifier: not a ISO3166 code
一直没有找到workaround，这个相关的bug【1】也没有被解决。今天升级了一下系统，内核升级到了4.7.3-200，问题任然存在。于是又搜索了一下，找到一个workaround【2】，把防火墙禁止掉，已经验证是有效的。上面的错误任然有，但是能正常关机。

After used Mac Pro more than one year as desktop, I bought a Dell XPS (13.3) laptop, and installed latest Fedora 24. Although I always use ubuntu/centos servers and ubuntu/fedora virtual machines, but the new system makes a exciting, the nature key shortcuts are very convenient.
Recommended some Gnome Extensions:
– Dash to Dock: use it to hold taskbar on the left side.

My friend Chun also loves my new system, he was shocked by big release number of Fedora, he still remember the days we were confused by unstable Feodra Core 5.
