Re: RTC drift in PPC

2007-06-05 Thread Theo Gjaltema
I 'v measured the clock on a mpc8280 board running the 2.4.25 kernel 
obtained from ELDK3.1.1, no problem with the clock during a test period 
of a few days.

 We are running RTC on mpc860 board with external crystal...
 We are getting 4 minutes drift for 21 hours.
 

 A slowdown in the approx. range 1:300 to 1:350 is endemic to linux ppc:
