<div>This page discusses the problem with /dev/rtc on certain models.<br />
<br />
== Problem description ==<br />
On bootup,a message like this shows up:<br />
<br />
<pre>select() to /dev/rtc to wait for clock tick timed out</pre><br />
<br />
<br />
The RTC kernel driver can't handle the system clock.<br />
<br />
== Possible solutions ==<br />
<br />
The '''hwclock''' command knows the parameter ''--directisa'' to access the system clock directly. To make this the default behavior, move /sbin/hwclock (or whereever it is located on your system) to '''/sbin/hwclock.dist''' and create the following shell script on the previous location:<br />
<pre>#!/bin/sh<br />
/sbin/hwclock.dist --directisa $*</pre><br />
Make the script executable (apply the same permissions you had for ''hwclock'' before) and keep your packaging system from overwriting it on updates.<br />
