Continuation of 92924224 — the same conditional-ack bug class found in
six more drivers: a foreign interrupt on a shared INTx line skipped the
write-back ack, leaving the kernel-masked IRQ line dead forever.
- sb16d, ac97d: ack before the not-ours continue
- rtl8139d, rtl8168d, ixgbed: ack unconditionally, tick only when ours
(the stale 'TODO: spurious interrupts' comments removed — the
spurious-interrupt confusion was this bug)
- ihdgd: ack unconditionally, handle_events/tick only when ours
Verified: cargo check -Z build-std --target x86_64-unknown-redox for
sb16d, ac97d, rtl8139d, rtl8168d, ixgbed, ihdgd — clean, no new
warnings. nvmed audited: not affected (per-queue MSI pattern, no
conditional ack).
Per local/docs/PATCH-PRESERVATION-AUDIT-2026-07-12.md the base
fork was carrying only 38 of 100 patches in local/patches/base/.
The other 62 patches' content was silently missing from the fork
working tree, even though their .patch files were preserved.
This commit re-applies 41 patches that genuinely still apply
cleanly + 17 hunks that partially applied. Recovery covers:
- D-Bus initfs service wiring (P4-initfs-dbus-services)
- USB service wiring (P4-initfs-usb-drm-services)
- netcfg/dhcp/dhcpv6 driver fixes
- acpid shutdown/PM/quirk fixes
- inputd/ps2d hard-fail logging
- pcid driver interface refinements (server cmd channel)
- virtio-core for VirtualBox support
- ixgbed/rtl8139/rtl8168 net drivers
- ahcid NCQ + per-function interrupt coalescing
- logd persistent logging
- bootstrap procmgr race-condition fixes
- cargo version pin to +rb0.3.0 (synchronized release branch)

Untracked mnt/ tree and *.orig / *.rej files cleaned up after
patch application (leftover from absolute-path patch headers).
