Hi Rajasekaran,

     Am working with PowerPc 8315rdb...and ma using recend version of
the kernel 2.6.26..but I found one problem with RTC m41t11..while trying
to read or set RTC which is already opened while booting itself,,,its
return the error message as resourse busy  with error no 29.. can u help
me to solve this issue,,,

Actually, I cannot help you right now, as I do not understand the
problem.  Can you perhaps show some log files and source code exhibiting
the problem?

What exactly are you trying to do?  Did you try enabling RTC_DEBUG in
the configuration (Device Drivers -> Real Time Clock -> RTC Debug
support)?  What do the kernel messages look like?

Cheers
  Detlev
