rtc error from dmesg

K.C. Chan — Tue, 24 Feb 2004 13:32:11 GMT

I am running kernel version: "2.4.18-3smp" and redhat 7.3. I am getting the following error from dmesg:
set_rtc_mmss: can't update from 50 to 4
set_rtc_mmss: can't update from 57 to 8
set_rtc_mmss: can't update from 57 to 9
set_rtc_mmss: can't update from 57 to 10
set_rtc_mmss: can't update from 57 to 11

I am runing ntp, I assume ntp is having trouble updating the system's real time clock? So when I check /proc/rtc, the file is not there? Any idea?

KC,

I think the absence of the file is significant.

I just this weekend upgraded my last Red Hat System to ES 3.0 so I can't check that for you.

If possible, compare the system to a working system. You might be able to copy the file, but it seems more likely that you'll need to reinstall the kernel.

If you have prior versions of the kernel, why not boot off that and see if the error repeats itself.

heh, dont copy anything in /proc, this is a virtual FS.
There are no "files" in there as such...

Hello K.C.,

maybe the following does help:

You might try setting CONFIG_RTC in the kernel and see if you have /dev/rtc and while your at it /proc/drivers/rtc.

I suggest you to upgrade to the latest RH recommended kernel for RHL 7.3 - 2.4.20
