Fast clock problem!

gaspra · 07-21-2005, 01:58 AM

I just got a problem with my compaq v2000z laptop. When I run linux X86_64 (CentOS with kernel 2.6.12.3) the system clock is almost 2~3 times faster than normal. When I run Windows XP, the system clock seems working correctly so I think this is not a problem with BIOS. I googled this problem and couldn't find a clue to solve it. Is there something wrong with the timer when I run linux? Can anyone help me to fix this problem? I really don't want to see this is year 2005 but my laptop shows year 2006.

I have no idea what is causing this! You should be able to check the hardware clock with the command hwclock. Assuming that is OK, and since you must be compiling your own kernel to be on 2.6.12.3, have you compiled in the real time clock (CONFIG_RTC=m or y)?

I can see some other RTC related options in there which I'm not familiar with, but which might be worth a try.

Otherwise, happy new year

Thanks, maroonbaboon, I did use CONFIG_RTC=y, so I think it might be some other issue. I have seen people solved the problem by setting boot option 'noapic' but I haven't tried it yet. Moreover I saw someone used 'acpi=off' but it didn't work for me. I think it might be some problem that X86_64 linux couldn't initialize the hardware properly.

[edit] Problem is solved by add "noapic" option!!! I am very happy I come back to 2005!
