Problem in timer interrupt handler with Linux 2.6.27 version

Problem in timer interrupt handler with Linux 2.6.27 version

[Asha R]

Hi All,

I am working on Linux 2.6.27 version.
I am facing problem in timer interrupt.

I get the timer interrupt but in the handler, evt->event_handler generates
prefetch abort.
The same code works with Linux 2.6.37 version.


Please let me know if anyone has faced this problem before.

Regards,
Asha

I dare to bet that if it was Greg KH that answered this first, you
will get the famous reply "we don't support old kernel version"....
and that's true...not that kernel folks abandon old kernel, it's just
making life so difficult...

Thanks for your response.
I am opting older version to use the Android cup cake version which is with
Linux 2.6.27.
On debugging more i have found that it is because clock related routines are
different in both versions.

Can someone help me to integrate, if done before?

Regards,
Asha
