Fix ratio boot issues: firmware, mkinitcpio, and document ZFS rollback dangers2026-01-22T20:27:49+00:00Craig Jenningsc@cjennings.net2026-01-22T20:27:49+00:00urn:sha1:8eb7eb600bc9e709b6ee754a337289382bbcea4f
Root cause: Missing/outdated linux-firmware broke AMD Strix Halo GPU init.
Fixed by installing linux-firmware 20260110-1.
Changes:
- install-archzfs: Fix mkinitcpio config (remove archiso.conf, fix preset)
- todo.org: Add ZFS rollback + /boot mismatch issue, recommend ZFSBootMenu
- docs/2026-01-22-ratio-boot-fix-session.org: Full troubleshooting session
- docs/2026-01-22-mkinitcpio-config-boot-failure.org: Bug report
- assets/: Supporting documentation and video transcript
Key learnings:
- AMD Strix Halo requires linux-firmware 20260110+
- ZFS rollback with /boot on EFI partition can break boot
- zpool import -R can permanently change mountpoints
