+已完成路由器本次闪断现场采集。2026-09-17 23:06:55 CST，AX9000 再次发生内核 Oops/panic 并在 3 秒后自动重启；pstore/ramoops 保存了完整 dmesg 与 console。PC 为 ip_skb_dst_mtu+0x90，调用链进入 IPv4 转发并由 qca_nss_drv 的 nss_core_handle_napi_queue 收包路径触发，当前最可疑是 NSS 硬件加速驱动与 Linux IPv4 MTU/转发路径交互。已将事实写入 MemRelay。下一步：基于匹配的 OpenWrt vmlinux 对 ip_skb_dst_mtu 偏移和 qca_nss_drv 版本做符号/源码核对，随后制定可回滚的规避方案（优先临时关闭 NSS 硬件流量加速或相关 flow offload）并持续采集验证；不要主动 panic 或重启，避免先修改无线配置。
