Comment (by severn):
I'm at a loss as to why it apparently works for nbd and me all the time,
only somewhat works for robnitro, and doesn't work for anon...
I've tested with r42328 and my original patch - same behaviour:
- VLAN routing (in eth0.x out eth0.y), (in eth1.x out eth1.y)
- "normal" routing in eth0.x out eth1, in eth1 out eth0.x
- with DHCP, over PPPoE, PPPoE over VLAN (on eth0.x or eth1)
- saturating the CPU with iperf TCP mode or UDP mode, simultaneous
bidirectional or just normal 1 direction upload
- speed test sites, regular browsing, etc.
...for the last few hours and I can't seem to reproduce the issues you
guys see.
In all cases, I had bridges on the eth0.x with a wifi, no bridges on the
eth1.x side, and I'm routing between interfaces (not bridging).
I have a laptop with gige on one port, and a managed switch on the other
port (either WAN/eth1 port or another vlan on a switch port) - tried
setting one or both to auto-negotiate 100meg full, or auto-negotiate gig
full, doesn't seem to make a difference.
1. Can you guys post full 'dmesg' with or without patch?
2. Post 'ifconfig' before and after the tx timeout error?
3. Can you tell me anything about your network setup (speed, what's on
each port, if you're auto-negotiating or forced speeds, etc.) and what
kind of traffic you're passing that's causes the error to show up?
4. Can you guys try using r42328 but change ag71xx.h AG71XX_TX_RING_SPLIT
to some other numbers, e.g. 128, 512, 1024?
5. Can you try commenting out lines 707 and 708 from r42328 and see if it
makes a difference?
This is my dmesg for comparison -
