Description Ben Kohler gentoo-dev 2014-01-23 02:16:45 UTC
For a while now, minimal install isos have all been missing CONFIG_RTC_CMOS so the hwclock service shows this output:

* Setting system clock using the hardware clock [UTC] ...
hwclock: Cannot access the Hardware Clock via any known method.
hwclock: Use the -debug option to see the details of our search for an access method.

This was fixed a while back in genkernel's default configs in bug #444932, but the releng installcd config is still missing CONFIG_RTC_CLASS and all RTC drivers under that menu.  See:

installcd-config-add-rtc.patch

Small correction to the above, the option is CONFIG_RTC_DRV_CMOS.  I've attached a config patch but really you just need to enter menuconfig and enable CONFIG_RTC_CLASS, that will auto-enable the CMOS driver.

It will autoenable CONFIG_RTC_HCTOSYS and CONFIG_RTC_SYSTOHC which I think should be off, but that's up for debate.

This should be fixed now.
