Hello Freescale guys! Can anyone help me with figuring out the resolution to the following kernel panic? This only happens after hours of playing video. Nothing seems to "trigger" it... just happens on its own.

 

Unable to handle kernel NULL pointer dereference at virtual address 00000000

pgd = 80004000

[00000000] *pgd=00000000

VPU interrupt received.

 

I could use some resolution ASAP.

 

This is kernel 1.1.1 and LTIB 1.1.0

 

Thanks
