OK

We've had couple of panics, so it seems that these doesn't affect the problem. We had 15 units running stress-ng and it took ~8 days until we saw first panic, so if omap2plus is affected it is quite rare.

Hmm so to confirm.. Is omap2plus_defconfig stable on all boards including your custom
board?

Maybe provide output of what changes make the problem happen with your custom
.config if you have not already done:

$ make savedefconfig
$ cp defconfig arch/arm/configs/omap2plus_defconfig
$ git diff
