Torrent traffic brings down wired net after a few minutes

Reported by: Del Owned by: developers
Priority: high Milestone: Chaos Calmer 15.05
Component: kernel Version: Trunk
Keywords: Cc:


After a few minutes of heavy torrent traffic, the wired network goes down. Wireless clients are still connected and work as before.

This is on the Mikrotik RouterBOARD 493G, running Barrier Breaker r35052. Dmesg is rather verbose on the problem, seems the problem hits at net/sched/sch_generic.c:255, google provides numerous hits on issues triggered there. The relevant part of dmesg is the following (complete dmesg attached):

Searched through tickets posted with OpenWrt. As far as I can see this issue is a recurrent one with the ag71xx with many similar reports. In the case of RB493G, it seems it is the switch AR8316 (from dmesg).

Other issues of the same kind include #12446, #6754 and #11933 in addition to at least three duplicates.
