# DF-3947 — Verification Verdict

**Status:** untested (Info-severity error-path finding; verification skipped per policy — hardware+BIOS-failure gated, no security impact beyond hygiene)
**Impact:** none demonstrated
**Confidence:** certain (source)

Source: set at dce110_hw_sequencer.c:2028, cleared only at :2084; the error
return at :2079-2081 (`if (DC_OK != status) return status;`) bypasses it.
Failure sources: dce110_hw_sequencer.c:1324-1330 (program_pix_clk false) and
:1399-1403 (crtc_source_select != BP_RESULT_OK).

No runtime test performed (no AMD GPU on the audit guest). fix.diff is the
one-line cleanup; kernel rebuild not warranted for an Info finding.

## Fix status (batch validation)
Applied with the 36 sibling fix.diffs of this batch in findings/poc/_batch41/all_fixes.patch; single in-guest `make -j6 nativekernel KERNCONF=X86_64_GENERIC` completed RC=0 with zero errors under -Werror (full log: findings/poc/_batch41/fix_build8.log). Behavior A/B intentionally skipped for this Info-tier item.
