<p></p> <p><b>New page</b></p><div>&#039;&#039;&#039;Q&#039;&#039;&#039;: Why does the system sometimes hang while reboot?<br /> <br /> &#039;&#039;&#039;A&#039;&#039;&#039;: &lt;ol&gt;&lt;li&gt;On newer busybox versions the command after a &#039;&#039;shutdown&#039;&#039; keyword from the &#039;&#039;/etc/inttab&#039;&#039; file will be executed, e.g.:<br /> &lt;pre&gt; ::shutdown:/sbin/halt&lt;/pre&gt;<br /> So a &#039;&#039;halt&#039;&#039; action will be followed by a &#039;&#039;reboot&#039;&#039; and the node will only executes the &#039;&#039;&#039;&#039;&#039;halt&#039;&#039;&#039;&#039;&#039; action.&lt;/li&gt;<br /> &lt;li&gt;A &#039;&#039;reboot&#039;&#039; is implemented by triggering a watchdog event. After writing to flash, the hardware watchdog failes in some cases.&lt;br&gt;An intensive read of the flash seems to solve that timing problem:<br /> &lt;pre&gt;$ cat /dev/mtdblock/3 &gt; /dev/null<br /> $ cat /dev/mtdblock/2 &gt; /dev/null<br /> $ reboot -f&lt;/pre&gt;&lt;/li&gt;<br /> &lt;/ol&gt;<br /> <br /> ----</div>
