Oh hai! I've created bugzilla ticket about this, but I'm not sure if anyone reads it, so duplicating here.
I have new motherboard (ASUS A320-K) with 10ec:8168 realtek network card installed and it doesn't work (i. e. `tcpdump` shows outgoing packets but no packets are actually transmitted and `tcpdump` doesn't show incoming packets while they are trasmitted from the other side) then after 200-300 seconds I see [full stacktrace [1] and lspci [2] output are attached to bugzilla ticket] [ 256.996145] ------------[ cut here ]------------ [ 256.997574] NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out [ 256.998992] WARNING: CPU: 6 PID: 0 at dev_watchdog+0x1f2/0x200 … [ 257.012243] RIP: 0010:dev_watchdog+0x1f2/0x200 … [ 257.032044] <IRQ> [ 257.033829] ? pfifo_fast_init+0x150/0x150 [ 257.035618] call_timer_fn+0x2b/0x120 [ 257.037400] run_timer_softirq+0x2f4/0x410 [ 257.039170] ? pfifo_fast_init+0x150/0x150 [ 257.040931] ? timerqueue_add+0x52/0x80 [ 257.042694] ? __hrtimer_run_queues+0x161/0x2e0 [ 257.044462] __do_softirq+0x111/0x32c [ 257.046223] irq_exit+0x85/0x90 [ 257.047966] smp_apic_timer_interrupt+0x6c/0x120 [ 257.049720] apic_timer_interrupt+0xf/0x20 [ 257.051475] </IRQ> and everything starts working normally. How can I make it work right after boot? The issue is reproducible in linux-4.16.5 & linux-4.17-rc2 with rtl_nic fw from linux-firmware git master.
