Public bug reported:
OS: Ubuntu Server 23.10.1
Filesystem: OpenZFS, latest version from Ubuntu Repo
GPU: Intel ARC A380, Codename DG2
i915 driver for ARC GPU fails to load if the "zfs" module is loaded first
during boot.
I noticed this by installing the package "zfsutils-linux" and rebooting the
server. Hardware acceleration in Jellyfin stopped working and "vainfo" command
failed.
See the following journalctl output:

I was able to "fix" it by configuring a soft dependency for the zfs module:
1. Create File '/etc/modprobe.d/i915_before_zfs.conf'
2. Add content: "softdep zfs pre: i915"
3. Reboot
4. Profit.
Obviously this is not a permanent solution, but forces the i915 driver
to load before the zfs module breaks it.
Here is the log output after the above mentioned "fix":
