Could you elaborate on your test scenario so that I can try and reproduce the problem at my end? Also, did you have the contents of my commit stack in this particular kernel build? Assuming that the DMA got stuck at some point leading up to the transmit timeout, any ideas as to why a host error was not thrown? To help debug, I'll post out a set of patches that dump out the MAC (and DMA) registers on timeout. That should give us some visibility into the problem. > [ 1651.440000] nfs: server 192.168.2.34 not responding, still trying > [ 1859.010000] ------------[ cut here ]------------ > [ 1859.010000] WARNING: at net/sched/sch_generic.c:258 > dev_watchdog+0x184/0x294() > [ 1859.020000] NETDEV WATCHDOG: eth0 (davinci_emac): transmit queue 0 timed > out [...] Regards Cyril. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
