Package: src:linux Followup-For: Bug #808889 Dear Maintainer, I am facing the same problem as the original bug reporter. Here some further information, which I hope helps further to find the problem. hwclock -r hwclock: ioctl(RTC_RD_TIME) to /dev/rtc to read the time failed: Invalid argument hwclock -w hwclock: ioctl(RTC_RD_TIME) to /dev/rtc to read the time failed: Invalid argument kern.log:Jan 1 01:00:15 x200 kernel: [ 0.093160] RTC time: 23:14:56, date: 01/01/-84 kern.log:Jan 1 01:00:15 x200 kernel: [ 0.795451] rtc_cmos 00:03: RTC can wake from S4 kern.log:Jan 1 01:00:15 x200 kernel: [ 0.795581] rtc_cmos 00:03: rtc core: registered rtc_cmos as rtc0 kern.log:Jan 1 01:00:15 x200 kernel: [ 0.795615] rtc_cmos 00:03: alarms up to one month, y3k, 242 bytes nvram, hpet irqs kern.log:Jan 1 01:00:15 x200 kernel: [ 0.804337] rtc_cmos 00:03: hctosys: unable to read the hardware clock kern.log:Jan 2 10:34:35 x200 kernel: [ 9769.320290] rtc_cmos 00:03: System wakeup disabled by ACPI kern.log:Jan 1 01:00:15 x200 kernel: [ 0.093159] RTC time: 13:16:25, date: 01/02/-84 kern.log:Jan 1 01:00:15 x200 kernel: [ 0.795543] rtc_cmos 00:03: RTC can wake from S4 kern.log:Jan 1 01:00:15 x200 kernel: [ 0.795672] rtc_cmos 00:03: rtc core: registered rtc_cmos as rtc0 kern.log:Jan 1 01:00:15 x200 kernel: [ 0.795706] rtc_cmos 00:03: alarms up to one month, y3k, 242 bytes nvram, hpet irqs kern.log:Jan 1 01:00:15 x200 kernel: [ 0.804701] rtc_cmos 00:03: hctosys: unable to read the hardware clock syslog.1:Jan 1 01:00:20 x200 kernel: [ 0.000000] clocksource: refined-jiffies: mask: 0xffffffff max_cycles: 0xffffffff, max_idle_ns: 7645519600211568 ns syslog.1:Jan 1 01:00:20 x200 kernel: [ 0.000000] WARNING: Persistent clock returned invalid value!
