I was able to solve the problem by booting with an old kernel, editing /etc/initramfs-tools/initramfs.conf and replacing
MODULES=most
with
MODULES=dep
and then running sudo update-initramfs -u.
I think the problem was that initramfs was including a module xhci-plat-hcd which is buggy and not really required. I was seeing error messages of the type
... xhci_hcd ... HC died; cleaning up
and then couldn't enter my passphrase.
