 |
|
Hi.
Recently I've received a AMD X2 4200+ machine. The installaton of Gentoo went through with no problems, but now I'm stuck some minor annoyances.
When the system is booting and comes to the stage where it is supposed the synchronise the system clock to the hardware clock, it fails:
* Setting system clock to hardware clock [Local Time] ...
* Cannot access the Hardware Clock via any known method.
Use the --debug option to see the details of our search for an access method.Cannot access the Hardware Clock via any known method.
Use the --debug option to see the details of our search for an access method.
* Failed to set system clock to hardware clock [ !! ]
If I run hwclock --debug:
hwclock from util-linux-2.12r
hwclock: Open of /dev/rtc failed, errno=2: No such file or directory.
No usable clock interface found.
Cannot access the Hardware Clock via any known method.
Enhanced Real Time Clock is enabled as a module. Generic /dev/rtc emulation is disabled because it fails to load as module. Should I enable compile it into the kernel? I also have Pentium-M clock where all the above settings are disabled yet the everything is working.
SOLUTION: I removed the nvnet driver from nvidia and used the forcedeth driver and now everything works. |

| yeah I'm getting the same error message, but I don't have RTC enabled in the kernel. Is this something I need to do, and/or what else do I need to do? |

Yes, You should enable RTC support (built-in will give you the least headaches) in the kernel and hwclock will be able to sync correctly. |

| Put the rtc module in /etc/modules.autoload.d/kernel-2.6. If that fails you probably don't have rtc in your kernel (built in or module) so specify and recompile it. |

not for me, i got RTC as module in my kernel, but at boot i can see its not getting loaded.. what can be the reason ?
i just put RTC into modules.autoload because of an ati-radeon hardware opengl HOWTO, my ati card is working pretty well but what can be the reason that the module cant be loaded ?
with friendly regards

Try a manual load:
and then see it has loaded with
Another possibility is that udev is not creating the rtc device node:
