Description Ken Nordquist 2005-04-16 14:21:38 UTC 
Description of problem:

System clock runs at 2x faster than it should.  From extensive Google searches,
it appears this is a problem w/ATI RS200 chipset and the kernel.  An excellent
thread outlining the problem can be found here:
http://kerneltrap.org/mailarchive/1/search/subject/clock%20runs%20at%20double%20speed%20on%20x86_64%20system%20w/ATI%20RS200%20chipset
 and confirmation of the problem can be found here:
http://scottstuff.net/scott/archives/000391.html

For my comparison purposes, I sync'd the hardware clock with the system clock by
'ntpdate pool.ntp.org && hwclock -w', waited approximately fifteen minutes and
ran 'hwclock --show' and compared it to the system clock.  The result is the
system clock was fifteen minutes ahead of the hardware clock.

The motherboard I use is the MSI RS480M2-IL. 



Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1.

Actual results:
System clock runs at 2x speed.

Expected results:
System clock to run at normal speed.

I mentioned this on the test list...  the Kanotix 32 bit distro
(http://kanotix.com/info/index.php) does not skew my clock.  I HTH.
