[gentoo-user] 2.6.26, rtc problem

[gentoo-user] 2.6.26, rtc problem

[Andrew Gaydenko]

Hi!

After upgrading to 2.6.26 I have got a problem with starting hwclock 
service - it doesn't find /dev/rtc. I have tried to add rtc_cmos 
to /conf.d/modules, but the module loads after the service starting. 

So, questions are:

1. How to force the module loading be before the service starting?

2. How to determine which concrete module is most appropriate to my hardware 
(there are plenty of rtc_xyz modules)?

I believe /etc/modules.d/* may do it. AFAIK it runs very early in the 
init sequence

Do not build it as module....

If your system does an autoloading of modules somewhere in time: just 
lsmod. Otherwise you have to try to load them all and take that one that 
does not complain about missing hardware... ;-)

If understand well, those files (in /etc/modules.d/) contain configuration 
options for modules rather a list of modules to load.

The was /etc/modules.autoload.d/kernel-2.6 file wich at some update point 
magically disappered. I think Gentoo developers suppose some replacement 
for this file.

I still have that file on one of my systems. My other system is running 
openrc which does not have that file but it does have /etc/conf.d/modules.

'hwclock' contains this fragment:

	ebegin "Setting system clock using the hardware clock [${utc}]"
	if [ -e /proc/modules -a ! -e /dev/rtc ]; then
		modprobe -q rtc || modprobe -q genrtc
	fi

But there are no such modules at all :-) I have installed openrc since 
april, but have got time-related problem only now.

I was just letting you know where the file moved to for auto-loading 
modules. I'm not sure why hwclock isn't loading the module. You could 
try changing the modprobe -q to modprobe -v. To make the output verbose.

If you need rtc_cmos every time you boot, why not build it into the
kernel. That way you can be sure it will be available to anything that
needs it.

At first, I frustrated with situation when I can not manage such things :-) 
Then, I don't understand the reason of the problem. And yet don't know is 
rtc_cmos the most appropriate choice.

In accordance with http://bugs.gentoo.org/show_bug.cgi?id=232343 - will 
anybody be so kind to attach (or send using direct emailing)
~amd64/x86_64/gentoo-sources-2.6.26 .config file with the CONFIG_GEN_RTC 
set? I have not found this flag in menuconfig - probably there are some 
dependencies I can not recognize.
