CPU core locked when RTC changed

Hi,

This is a very strange bug. :smileyhappy:

We've upgraded from 3.0.35 to 3.14 (on Lollipop 5.1.1-ga) and are experiencing problems with the CPU getting locked up when clock/date is changed. But only one of the cores, and eventually watchdog triggers restart.

This only happens if the unix time set is above 268435456 (0x10000000), setting anything below that works fine.

In other words; the following command works fine.

date -s 19780704.212400

But if running.

date -s 19780704.212500

One of the CPU cores gets locked up.

Anyone has any idea what goes wrong?

We're running on iMX6DL, and kernel 3.0.35 works fine.

Best regards,

Emil

Fixed! Problem was in our code and differences in 3.0.35 vs 3.14.
