Is your RTC driver compiled into the kernel? The "httosys" function of |
78 |
the kernel takes place before any modules can be loaded and will fail if |
79 |
your CMOS clock driver is a module. |
80 |
|
81 |
Activating clock_hctosys in /etc/conf.d/hwclock should solve this as it |
82 |
takes place later in the boot process. |
