ARM (IMX) devices booting/LPAE

[Ryan]

Hi Jason,

Thanks,

I tried all three both previously and again on receipt of your response
(Incase i made a simple error somewhere) and the outcome is the same,
it goes to kernel panic.

I tried variations of the /dev/mmcblk1p1 foot INITRD = xxx which was
working on the early kernels and this made no difference either.

The initrd.img for these is there and created on install and I have
tried regeneating it, also I explicitdly named the vmlinux-x.x.x and
initrd.img-x.x.x for the failing kernels and it does not boot like
before.

Is there any major config change between 6.12 and 6.18 that could be
behind this?

Regards

Ryan
