At least, we need a pretty good explanation of what exactly is causing
these spurious aborts before we start ignoring them unconditionally like
this. You're effectively masking an extremely serious error indicator with
this change.

This fault occurs once every boot sometime early in the boot process,
but the actual time this happens varies randomly.

Well that's interesting in itself. It sounds like we don't know *for sure*
whether the abort is triggered by Linux. Since the abort is imprecise, the
timing will vary.

It might be possible to find out the culprit if you just enter an endless loop
in the early kernel boot code. If you enter the loop before Linux does something
wrong, it won't crash, otherwise it will. After that, you could bisect the
boot process by moving the busy loop around.

If it even crashes at the point where Linux gets entered, it's a bug in the
boot loader.

Can you give Arnd's suggestion a go please Hauke?

Thanks,

Will
