 |
|
Hi,
I am currently trying out gentoo. I have not build my own kernel, but I rather used the genkernel script to build it for me. Now on my machine my clock is always off by exactely 1 hour.
My hardware clock is using UTC, whereas I am at UTC+1 currently, so it is quite clear where the one hour difference comes from. I enabled rc logging and I found the following message in my rc.log:
| Code: | * Setting system clock using the hardware clock [UTC] ...
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.
* Failed to set the system clock
[ !! ]
|
If I do a hwclock --debug it complains that it could not find /dev/rtc.
I looked around online and some postings said RTC had to be enabled in the kernel. However looking at my .config in the kernel directory I get:
| Code: | zion linux # cat /usr/src/linux/.config | grep -i RTC
# CONFIG_RTC is not set
# CONFIG_GEN_RTC is not set
# CONFIG_RTC_CLASS is not set |
Does this mean that RTC support is not correctly in the kernel I configured using genkernel? Is this a bug in the genkernel?
Or is there some other reason for my clock problems, that I can fix without building my own kernel? |

Hi, it used to be, but then when it became kernel 3.x it was disabled. Now I use:
| Code: | | genkernel --menuconfig all |
and enable the RTC stuff that I used to have in my previous 2.6.39-x kernel.
