Rare kernel panic

pradeepkarosiya — Tue, 11 Sep 2012 12:27:38 GMT

Hi,

I've customize board derived from MX28EVK. I'm running linux application based on kernel 2.6.35.3 most of the time the app is working fine.

But after prolong running the kernel crashes and issues kernel panic. I've attached one of the log.

Any help or direction will be highly appreciable.

Thanks in advance .
