一个奇怪的ARM网络通信崩溃问题：ARM和电脑的通信信连接后ARM会报错

问答对人有帮助，内容完整，我也想知道答案 0 背景：ARM和电脑的通信：1.在iTOP-4412上安装了Linux最小系统，并自己写了基于TCP/IP的网络通信程序 2.在电脑基于C#编写的界面程序问题：两者建立通信连接后ARM会报错错误信息： [ 2883.010078] ------------[ cut here ]------------ [ 2883.013314] WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0x3c0/0x3d0() [ 2883.020526] NETDEV WATCHDOG: eth0 (dm9620): transmit queue 0 timed out [ 2883.027182] Modules linked in: char_driver_leds [ 2883.031494] Backtrace: [ 2883.033992] [] (dump_backtrace+0x0/0x11c) from [] (dump_stack+0x18/0x1c) [ 2883.042395] r6:c0897aec r5:000000ff r4:c08cbda0 r3:c08ca000 [ 2883.048041] [] (dump_stack+0x0/0x1c) from [] (warn_slowpath_common+0x5c/0x6c) [ 2883.057071] [] (warn_slowpath_common+0x0/0x6c) from [] (warn_slowpath_fmt+0x38/0x40) [ 2883.066352] r8:0007e1f9 r7:c09a510c r6:c08cc080 r5:00000000 r4:d48b0000 [ 2883.072812] r3:00000009 [ 2883.075461] [] (warn_slowpath_fmt+0x0/0x40) from [] (dev_watchdog+0x3c0/0x3d0) [ 2883.084396] r3:d48b0000 r2:c0897b04 [ 2883.087972] [] (dev_watchdog+0x0/0x3d0) from [] (run_timer_softirq+0x140/0x24c) [ 2883.097029] [] (run_timer_softirq+0x0/0x24c) from [] (__do_softirq+0xc8/0x198) [ 2883.105955] [] (__do_softirq+0x0/0x198) from [] (irq_exit+0xb4/0xb8) [ 2883.114032] [] (irq_exit+0x0/0xb8) from [] (ipi_timer+0x48/0x4c) [ 2883.121873] r4:c003c040 r3:00000001 [ 2883.125293] [] (ipi_timer+0x0/0x4c) from [] (do_local_timer+0x68/0x84) [ 2883.133527] r6:00000000 r5:c003cdec r4:c08da8f0 r3:c0992c20 [ 2883.139163] [] (do_local_timer+0x0/0x84) from [] (__irq_svc+0x80/0x14c) [ 2883.147508] Exception stack(0xc08cbef8 to 0xc08cbf40) [ 2883.152685] bee0: cfa2f887 00000000 [ 2883.160731] bf00: 32a755fd 000cf7a3 c097011c c09a2ce8 c11b60b8 c08e30ac 4000406a c11b60a8 [ 2883.168878] bf20: 00000000 c08cbf64 033de8d4 c08cbf40 31c51bdf c005b730 80000013 ffffffff [ 2883.177013] r7:00000002 r6:0000001c r5:f8810000 r4:ffffffff [ 2883.182669] [] (exynos4_enter_idle+0x0/0x17c) from [] (cpuidle_idle_call+0xac/0x12c) [ 2883.192287] r5:c09a2ce8 r4:c11b60a8 [ 2883.195676] [] (cpuidle_idle_call+0x0/0x12c) from [] (cpu_idle+0xd0/0x104) [ 2883.204268] r9:413fc090 r8:4000406a r6:c05a049c r5:c096fa84 r4:c08ca000 [ 2883.210772] r3:00000000 [ 2883.213391] [] (cpu_idle+0x0/0x104) from [] (rest_init+0xa4/0xa8) [ 2883.221333] r7:7fffffff r6:c0038594 r5:00000002 r4:c08ca000 [ 2883.226835] [] (rest_init+0x0/0xa8) from [] (start_kernel+0x3b8/0x3c4) [ 2883.235085] r5:c096f9c0 r4:c08da7b4 [ 2883.238628] [] (start_kernel+0x0/0x3c4) from [<40008044>] (0x40008044) [ 2883.246026] ---[ end trace df29793856d8955f ]--- 不知道该如何解决，有遇到过类似情况的大神么？ 0 已退回1积分
