Errors with /etc/init.d/hwclock

[Sandro]

Hi To All Dear _Funtoo Users.

ci74771ht ~ # cat /etc/conf.d/hwclock 
# Set CLOCK to "UTC" if your Hardware Clock is set to UTC (also known as
# Greenwich Mean Time).  If that clock is set to the local time, then
# set CLOCK to "local".  Note that if you dual boot with Windows, then
# you should set it to "local".
clock="local"
 
# If you want the hwclock script to set the system time (software clock)
# to match the current hardware clock during bootup, leave this
# commented out.
# However, you can set this to "NO" ifyou are running a modern kernel
# with CONFIG_RTC_HCTOSYS set to y and your hardware clock set to UTC.
clock_hctosys="YES"
 
# If you do not want to set the hardware clock to the current system
# time (software clock) during shutdown, set this to no.
clock_systohc="YES"
 
# If you wish to pass any other arguments to hwclock during bootup,
# you may do so here. Alpha users may wish to use --arc or --srm here.
clock_args=""

 

But I got errors either at startup then in the shutdown:

 

hwclock: Cannot access the Hardware Clock via any known method.
hwclock: Use the --debug option to see the details of our search for an access method.
 * ERROR: hwclock failed to stop
hwclock: Cannot access the Hardware Clock via any known method.
hwclock: Use the --debug option to see the details of our search for an access method.

 

There is a way to solve ?

 

Thank You !!!!

So.... the trouble is in my kernel-config ?

Yes!

Configure the kernel with menuconfig following this path:

Device Drivers

Real Time Clock

*** Platform RTC drivers ***

PC-style 'CMOS'

I compile as <M> kernel module.

Rebuild kernel and install.

hwclock communicates with cmos clock on bios motherboard using /dev/rtc

Thanx for answer; but: I've these outputs:

ci74771ht ~ # hwclock --debug

hwclock: impossibile aprire /dev/rtc: File o directory non esistente
Impossibile trovare un'interfaccia clock utilizzabile.

util-linux is installed.

 

So.... the trouble is in my kernel-config ?

(forgive my ignorance) !!!! :(

Great cardinal :)

 

Now it's ok.

 

No errors on startup & shutdown !
