The latest Gentoo-LiveDVD 11.2 doesn't have RTC drivers, then hwclock cannot get the system time correctly: Gentoo-11 ~ # /sbin/hwclock Cannot access the Hardware Clock via any known method. Use the --debug option to see the details of our search for an access method. Gentoo-11 ~ # /sbin/hwclock --debug hwclock from util-linux 2.19.1 hwclock: Open of /dev/rtc failed, errno=2: No such file or directory. No usable clock interface found. Cannot access the Hardware Clock via any known method. Gentoo-11 ~ # grep ^CONFIG_RTC /kernel-config-x86_64-2.6.39-gentoo-r4 CONFIG_RTC_LIB=m CONFIG_RTC_CLASS=m CONFIG_RTC_INTF_SYSFS=y CONFIG_RTC_INTF_PROC=y CONFIG_RTC_INTF_DEV=y CONFIG_RTC_INTF_DEV_UIE_EMUL=y CONFIG_RTC_DRV_DS1374=m CONFIG_RTC_DRV_MAX6900=m CONFIG_RTC_DRV_M41T80=m CONFIG_RTC_DRV_M41T80_WDT=y CONFIG_RTC_DRV_CMOS=m CONFIG_RTC_DRV_DS1553=m CONFIG_RTC_DRV_DS1742=m CONFIG_RTC_DRV_STK17TA8=m CONFIG_RTC_DRV_M48T86=m CONFIG_RTC_DRV_M48T59=m CONFIG_RTC_DRV_V3020=m Gentoo-11 ~ # grep RTC /usr/src/linux-3.0-gentoo-r1/.config # CONFIG_RTC is not set # CONFIG_GEN_RTC is not set # CONFIG_RTC_CLASS is not set On x86 computers, I think this one is mostly needed, CONFIG_RTC_DRV_CMOS=m But I don't understand why there are two different "/kernel-config-x86_64-2.6.39-gentoo-r4", "/usr/src/linux-3.0-gentoo-r1/.config" on the LiveDVD ?
even no any rtc related kernel modules: Gentoo-11 ~ # modprobe -l |grep rtc Gentoo-11 ~ #
Same with 2012 multilib amd64: /sbin/hwclock Cannot access the Hardware Clock via any known method. Use the --debug option to see the details of our search for an access method. Gentoo-11 ~ # /sbin/hwclock --debug hwclock from util-linux 2.20.1 hwclock: Open of /dev/rtc failed: No such file or directory. No usable clock interface found. Cannot access the Hardware Clock via any known method. and from livecd .config: #CONFIG_RTC is not set #CONFIG_GEN_RTC is not set
thanks for reporting this, not sure how this was disabled.
fixed, thanks for reporting.
