## Verdict

Source-confirmed: ata_serialize uses static int inited (:212) to guard allocation; racy across multiple controllers; device_set_ivars stores on shared PCI dev; ATA-HW-gated

## Fix Status

Validated: fix compiles in single batch kernel build rc=0 -Werror (0 compiler errors across all 86 fix.diffs)

## Source File

`sys/dev/disk/nata/chipsets/ata-acard.c`

## Fix Validation

All 87 fix.diffs compiled together in a single batch kernel build
