I checked three times: # cat /proc/driver/rtc rtc_time : 16:13:52 rtc_date : 2011-03-21 alrm_time : 00:00:00 alrm_date : 1970-01-01 alarm_IRQ : no alrm_pending : no 24hr : yes periodic_IRQ : no update_IRQ : no HPET_emulated : no BCD : no DST_enable : no periodic_freq : 1024 batt_status : dead # cat /proc/driver/rtc rtc_time : 16:13:59 rtc_date : 2011-03-21 alrm_time : 00:00:00 alrm_date : 1970-01-01 alarm_IRQ : no alrm_pending : no 24hr : yes periodic_IRQ : no update_IRQ : no HPET_emulated : no BCD : no DST_enable : no periodic_freq : 1024 batt_status : okay # cat /proc/driver/rtc rtc_time : 16:14:10 rtc_date : 2011-03-21 alrm_time : 00:00:00 alrm_date : 1970-01-01 alarm_IRQ : no alrm_pending : no 24hr : yes periodic_IRQ : no update_IRQ : no HPET_emulated : no BCD : no DST_enable : no periodic_freq : 1024 batt_status : okay -- Note that at the first time, it said "batt_status: dead", but then changed to okay. But the most interesting of all, that after this (not doing anything else) "hwclock --systohc" and "hwclock -r" started to work with no error. And they now continue to work also across a reboot and poweroff. Strange, but well, ok. :) -- With respect, Roman
