E: Error installing CMOS-RTC region handler

I could not find the right topic under which this would go, and decided to put it in my corner since I may be forgiven such a slight indiscretion here.

On wake up from suspend I get an error

Error installing CMOS-RTC region handler

Internet searches revealed nothing but source code and from this I deduced that it is something that has to load the region handler on an ACPI namespace scan.

Upon further investigation it seems that on x86 architectures the RTC gets handled differently on boot and that is why this error only occurs at resume after suspend.

Could someone perhaps point me in an appropriate direction regarding this?

Hey, so I don't use suspend and yet with the 3.15.4 and 3.15.5 kernels, I get this on each boot (be it cold boots or restarts) on my work laptop (an Intel i3-2370M):

dmesg | grep CMOS-RTC
[   13.718504] ACPI: Error installing CMOS-RTC region handler

I don't remember seeing it with 3.15.3 or before that and it's not happening with any of the LTS series of kernels that I run or with 3.15.0-1-ARCH. So, I reckon it's a kernel update. Let me downgrade and report back.

Reporting back: I have it with 3.15.3/4/5-ARCH, 3.15.3/4/5-lqx AND 3.15.3/4/5-ck-pax but not 3.15.2 or any patched version before that. I reckon it's a kernel bug introduced with 3.15.3.

@hzy199411, gremble: Could the both of you please try downgrading your kernels (no need to try other branches, just the ones your currently using) through the various versions and report back please?

Claire is fine.
Problems? I have dysgraphia, so clear and concise please.

Re: E: Error installing CMOS-RTC region handler

I have the same problem however it may not be kernel related i suppose but rather systemd/vhba-module related i think and this is why

I upgraded from 3.15.1 to 3.15.5 but i didnt get this specific error message instantaneouly, at first i got another error at boot where systemd fails to start the systemd-modules-load.service due to an error in inserting vhba module specifically.

I was searching for an answer  to that problem however during my search a new version of vhba-module came out so i upgraded and the error message disappeared and now vhba module is loaded with the other modules however now I get the same error you guys are having so I guess it is a related problem

Re: E: Error installing CMOS-RTC region handler

@clfarron4: Hey, I have the same behaviour as you and can confirm it appears w/ 3.15.3 here as well.
(It's a laptop as well HP Pavilion dv6, i5-2410M. Not using systemd.)

Though everything works (!) it's just the message appearing on console at boot and when switching from X, and it's also in dmesg.

So, I would agree it's some sort of bug... maybe they could change this to a warning or so, that it just doesnt appear, (bug-) report ?

Re: E: Error installing CMOS-RTC region handler

Hmm... As much as I want to perform a git bisect on the kernel from 3.15.2 to 3.15.3 to make a decent kernel bug report, it will take lots of time (something I don't have right now) to find to find the offending commits.

Re: E: Error installing CMOS-RTC region handler

Okay, yeah. Here it's not time but I'm not huugely motivated to start a bisect because of this. But I think I'll make a report, maybe they can degrade the message to a warning (no idea if that's possible), I wouldn't bother having it in the logs... this way avoiding a bisect smile...

And I've got another issue on another machine that I want to bisect, so maybe when I can manage to set up some "decent" workflow to do so, I'll do it then.

Re: E: Error installing CMOS-RTC region handler

Hmph... So I upgraded to the 3.16-2 in [testing] and it's now gone.

Re: E: Error installing CMOS-RTC region handler

Ah, good, I didn't do anything yet.. big_smile

Apparently this: "usually this small issues tend to come and go," was good advice, from the other thread: https://bbs.archlinux.org/viewtopic.php … 2#p1442852
Even if it did refer to messages inside the log.
