Try adding thunderbolt.host_reset=0 to your kernel command line.
Suspect it's the changes that came in
https://launchpad.net/ubuntu/+source/linux/6.8.0-38.38:
- thunderbolt: Introduce tb_port_reset()
- thunderbolt: Introduce tb_path_deactivate_hop()
- thunderbolt: Make tb_switch_reset() support Thunderbolt 2, 3 and USB4
routers
- thunderbolt: Reset topology created by the boot firmware
These changes were done to fix a number of other issues with re-using
boot firmware settings. That kernel command line option will align it
with old behavior as a workaround.
I feel that a "correct" solution for your issue would be for
'thunderbolt.ko' and boltd to be included in the initramfs so that the
reset happens before the rootfs is mounted.

Title:
I can no longer boot from my Thunderbolt disk

Bug description:
Description: Ubuntu 24.04.1 LTS
Release: 24.04
Package: linux-image-6.8.0-41-generic
Since the kernel 6.8.0-36 has been updated to a newer version, I can no
longer boot from my Thunderbolt disk. Even with the current kernel 6.8.0-41 it
does not work.
If I boot with the old kernel 6.8.0-36 it still works, but I don't
want to work with it forever.
