On my Gentoo hppa systems with custom kernels, I get the following
error on bootup:
* Setting system clock using the hardware clock [UTC] ...
hwclock: settimeofday() failed: Invalid argument
* Failed to set the system clock
Once the system has booted up, hwclock --hctosys and hwclock --systohc
work fine. Maybe something related to gentoo /etc/init.d/hwclock but
before reporting it there I want to understand it first.
What RTC driver and options should be selected in the kernel for RTC
operations to work?
I have only RTC_DRV_GENERIC set for RTC drivers.
CONFIG_RTC_LIB=y
CONFIG_RTC_CLASS=y
CONFIG_RTC_HCTOSYS=y
CONFIG_RTC_HCTOSYS_DEVICE="rtc0"
CONFIG_RTC_SYSTOHC=y
CONFIG_RTC_SYSTOHC_DEVICE="rtc0"

I don't see this on debian...

I have pretty much the same config options:
CONFIG_RTC_LIB=y
CONFIG_RTC_CLASS=y
CONFIG_RTC_HCTOSYS=y
CONFIG_RTC_HCTOSYS_DEVICE="rtc0"
CONFIG_RTC_SYSTOHC=y
CONFIG_RTC_SYSTOHC_DEVICE="rtc0"
CONFIG_RTC_INTF_SYSFS=y
CONFIG_RTC_INTF_PROC=y
CONFIG_RTC_INTF_DEV=y
CONFIG_RTC_I2C_AND_SPI=y
CONFIG_RTC_DRV_GENERIC=y
The only difference seems to be that I don't have
CONFIG_RTC_INTF_DEV_UIE_EMUL=y

I see it at shutdown (32bit kernel):
hwclock: ioctl(RTC_SET_TIME) to /dev/rtc0 to set the time failed.: Invalid argument
