16:00:19.171 band mode=3 确认双频
16:00:19.178 ch1 开始 —— 2.4G 段共扫出 10 个 AP（ch1/6/11/13）
16:00:24.529 ch36 开始 —— 5G 段；ch36=XMDZ-5G(-71)、ch44=HUAWEI(-44)
ch52~144 全部为 DFS 被动扫描（驱动日志 dur<360,360>），无 AP
16:00:39.158 ch149 开始 —— UNII-3 第一个信道，type=active
16:00:39.2 【死机】驱动日志打印到一半被截断，CPU_LOCKUP
16:00:39.648 重启，回放：reset reason=15(CPU_LOCKUP)，stage=11 param=149 t=40344ms

扫描统计：死机前完成 40 个信道（约 20.3 秒），累计 12 个 AP；期间空闲堆稳定在 78.5KB、最小堆 76448 字节无异常波动。
