it's not clear to me if this is a real workaround/fix, but changing the
hwclock call to:
hwclock --systz
works without error
man hwclock says:
--systz
This is an alternate to the --hctosys function that does not
read the Hardware Clock nor set the System Clock; consequently
there is not any drift correction. It is intended to be used in
a startup script on systems with kernels above version 2.6 where
you know the System Clock has been set from the Hardware Clock
by the kernel during boot.
So what I seem to understand is that with recent kernels, the job of
syncing the system clock with the hardware clock is done at boot by the
kernel (you must have configured the kernel with CONFIG_RTC_HCTOSYS=y and
CONFIG_RTC_SYSTOHC=y). "hwclock --systz" performs additional tasks
(system clock correction to UTC, setting kernel's NTP '11 minute mode'
timescale (?), setting kernel's timezone).
As a matter of fact, I'm runnig with "hwclock --systz" in my setclock
bootscript since quite a bit and didn't notice any problem
