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:
 and confirmation of the problem can be found here:

For my comparison purposes, I sync'd the hardware clock with the system clock by
'ntpdate && 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:

Boot the computer.

Steps to Reproduce:
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
( does not skew my clock.  I HTH.
