Problems with hwclock
This page discusses the problem with /dev/rtc on certain models.
On bootup,a message like this shows up:
select() to /dev/rtc to wait for clock tick timed out
The RTC kernel driver can't handle the system clock.
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:
#!/bin/sh /sbin/hwclock.dist --directisa $*
Make the script executable (apply the same permissions you had for hwclock before) and keep your packaging system from overwriting it on updates.
