Yes, unlike the default Debian build, this one has 4 KiB page size.
It's not a solution, but it's a workaround for those affected by the bug
and perhaps a clue to the issue.

As your machine is booting regular 5.3 as well and seems not affected by
the bug, can you share some details about it? (exact model, number
of cores, ...).

No surprise, I think the on-disk format for the swap space hardwire
the page size. There's even a '-p' option to 'mkswap' to specify a
page size when creating the swap space.

Cordially,
