You can lower the delay in rtl8169_schedule_work (4) but it is akin to papering over the issue. You may try the stuff below in place of the current patch. I will not be surprized if the link really hangs (no crash but no traffic).

I've send and received 60 GB to and from the system and the performance is ~30 MB/s. I'll keep the system up and running and do some more stability tests. The only thing that's missing now is the transfer LED: the yellow link LED is on, but the green transfer LED is off and doesn't blink. Thanks a lot for your great support.

* [PATCH 1/2] r8169: Rx FIFO overflow fixes. 2011-12-01 22:26 ` Francois Romieu @ 2011-12-05 6:30 ` Francois Romieu 2011-12-05 23:45 ` David Miller 2012-02-20 2:37 ` Jonathan Nieder 2011-12-05 6:30 ` [PATCH 2/2] r8169: fix Rx index race between FIFO overflow recovery and NAPI handler Francois Romieu 1 sibling, 2 replies; 25+ messages in thread From: Francois Romieu @ 2011-12-05 6:30 UTC (permalink / raw) To: booster Cc: hayeswang, 'Jonathan Nieder', 'Eric Dumazet', netdev, 'nic_swsd', linux-kernel, 'Armin Kazmi' Realtek has specified that the post 8168c gigabit chips and the post 8105e fast ethernet chips recover automatically from a Rx FIFO overflow. The driver does not need to clear the RxFIFOOver bit of IntrStatus and it should rather avoid messing it. The implementation deserves some explanation: 1. events outside of the intr_event bit mask are now ignored. It enforces a no-processing policy for the events that either should not be there or should be ignored. 2. RxFIFOOver was already ignored in rtl_cfg_infos[RTL_CFG_1] for the whole 8168 line of chips with two exceptions: - RTL_GIGA_MAC_VER_22 since b5ba6d12bdac21bc0620a5089e0f24e362645efd ("use RxFIFO overflow workaround for 8168c chipset."). This one should now be correctly handled. - RTL_GIGA_MAC_VER_11 (8168b) which requires a different Rx FIFO overflow processing. Though it does not conform to Realtek suggestion above, the updated driver includes no change for RTL_GIGA_MAC_VER_12 and RTL_GIGA_MAC_VER_17. Both are 8168b. RTL_GIGA_MAC_VER_12 is common and a bit old so I'd rather wait for experimental evidence that the change suggested by Realtek really helps or does not hurt in unexpected ways. Removed case statements in rtl8169_interrupt are only 8168 relevant. 3. RxFIFOOver is masked for post 8105e 810x chips, namely the sole 8105e (RTL_GIGA_MAC_VER_30) itself.

Few guidelines are needed: go for it. I would trust the manufacturer for (3) though. If you still have time to help, you should really try to break davem-next branch. I won't claim it's bug-free but the IRQ / napi / Tx processing in the r8169 driver should now be easier to read and maintain. -- Ueimor ^ permalink raw reply [flat|nested] 25+ messages in thread
