#18922: eth1 (ag71xx): transmit queue 0 timed out ------------------------+-------------------------------- Reporter: fpv2000@… | Owner: developers Type: defect | Status: reopened Priority: normal | Milestone: Chaos Calmer 15.05 Component: kernel | Version: Trunk Resolution: | Keywords: ------------------------+--------------------------------
Comment (by ivaradi): I applied the patch to CC and have tested it for 4 days with heavy traffic. So far the softirq storm has not appeared (and neither was the TX_STATUS_PS getting stuck phenomenon detected). So I think the patch solves this issue. What I detected though was the DHCPv4 problem described above and eth0 (the LAN ports) getting stuck completely (i.e. no traffic at all, though wifi and the WAN port continued to work properly). They can both be resolved by resetting the interface with ifconfig up/down. They also appeared earlier as well, so they are not caused by the patch and are probably unrelated to this issue. I guess the issue of eth0 getting completely stuck might be a case of DMA getting stuck not detected by the current check. Do you think this could be the case, i.e. is it worth trying to debug with this assumption? The DHCPv4 problem is quite baffling as other traffic seems to be unaffected, and it also appears quite rarely... -- Ticket URL: <https://dev.openwrt.org/ticket/18922#comment:39> OpenWrt <http://openwrt.org> Opensource Wireless Router Technology _______________________________________________ openwrt-tickets mailing list openwrt-tickets@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-tickets
