6.0 GENERIC.MP kernel is labeled RAMDISK_CD

[shep]

My 5.9 -> 6.0 upgrade went smoothly on an i386 laptop but I am having issues with the same upgrade on my amd64 desktop. The install kernels, and the patched kernel I build show as a RAMDISK_CD as the top entry in the dmesg. Only one core of my dual core system appears configured.

I SHA256'd my sys.tar.gz/src.tar.gz and it was not mangled during download.

Anyone else having this problem?
