My comment was about the kernel sizes listed in the error msg:

 "ERROR: This kernel (size=90230265 > 16777216) is too big for your..."

Not knowing about the specific machine I can only guess this kernel is
embedding an initramfs for some specific purpose...but in my
experience I've never ever seen such huge sizes for a kernel.

Perplexed...
