hvc0 is the xen console. That grub line tells *all* kernels to use it.
That doesn't go well for a kernel that doesn't have xen, obviously.
The "right" way would be to get grub to only add those commands for
xen entries but you'd have to look in the docs to see if/how you can
do that.

use
GRUB_CMDLINE_LINUX_XEN_REPLACE_DEFAULT="console=hvc0 earlyprintk=xen"
in your /etc/defaults/grub to only use the line with zen kernels.
