2026-09-17 23:06:55 CST 再次确认路由器自动崩溃重启。持久日志与 pstore/ramoops 捕获完整 Oops:CPU 2 swapper/2,内核 6.12.91,ESR 0x96000006,访问地址 ffff ff800031f118,PC/LR 位于 ip_skb_dst_mtu+0x90/+0x8c;调用链为 __ip_finish_output -> ip_finish_output -> ip_output -> ip_forward_finish -> ip_forward -> ip_rcv -> bridge receive -> nss_core_handle_napi_queue [qca_nss_drv] -> net_rx_action;随后 Kernel panic - not syncing: Oops: Fatal exception in interrupt,3 秒后自动重启。说明闪断对应整机内核崩溃,当前最可疑边界是 qca_nss_drv/NSS 收包与 Linux IPv4 路由 MTU 路径交互,而非单一 Wi-Fi 客户端掉线。pstore 文件 dmesg-ramoops-0/1、console-ramoops-0 均含完整现场;当前启动后 uptime 23 分钟。未修改无线配置、未主动触发 panic。
