Can you try ami-500d8546 i us-east-1 and let me know if that works for
the c4.8large ?
I've asked, a few times, for the CentOS Linux images in AMP to be
enabled for all instance types where the image will work. So if its not
being enabled, there is a chance the image isnt suitable, and we should
find out why.
My recollection is that the official AMI still ships kernel -431, which breaks during boot on large systems with multiple NUMA nodes, like c4.8xlarges. This kernel is extremely old, and 'yum update' is enough to make everything work.
That used to be enough, and you could build an up to date AMI on top of the official one, but since they added the marketplace blacklist you need to roll your own AMI from scratch.
