Bug#465816: I forgot to mention which part of syslog to look at.
The relevant part(s) of syslog are the ones that read:
Feb 15 11:15:20 hades kernel: eth1: txs packet size do not coinsist with
txd
txd_:0x0000a520, txs_:0x000105be!
Feb 15 11:15:20 hades kernel: txd read ptr: 0x33c
Feb 15 11:15:20 hades kernel: txs-behind:0x800105be
Feb 15 11:15:20 hades kernel: txs-before:0x000105be
Feb 15 11:15:20 hades kernel: eth1: txs packet size do not coinsist with
and
txd_:0xefca5297, txs_:0x20000656!
Feb 15 11:15:20 hades kernel: txd read ptr: 0x1edc
Feb 15 11:15:20 hades kernel: txs-behind:0x000105be
Feb 15 11:15:20 hades kernel: txs-before:0x0005019c
Feb 15 11:15:27 hades kernel: NETDEV WATCHDOG: eth1: transmit timed out
Feb 15 11:15:28 hades kernel: ATL2: eth1 NIC Link is Up<100 Mbps Full
Duplex>
Notice on the last two lines the netdev watchdog kicks in. This causes the
connection to be reset and the transmission continues for a few more
seconds until it gets jammed up again. It may not be obvious from the bug
report but this causes the transfer speed over ethernet to drop
dramatically. This only happens on local network transfers because (I'm
guessing) that's the only time the interface is saturated.
