[3c509] 3c509B TCP overflow trouble

[Marco Emilio Poleggi]

Hi all,
I noticed an anomalous behaviour of my 3c509B TCP ("combo") card: it gets stuck 
intermittently (can't receive nor transmit) for some minutes. This happens on 
both the connectors (UTP and BNC), and the log reports only this line:

  kernel: _M_str_putnext: queue overflow: dropping a message

I tried to enlarge the /proc/sys/net/core/netdev_max_backlog, but nothing 
changed (only the kernel messages disappered!).
I compiled statically the module on a 2.4.5 kernel. I noticed the same trouble 
on a 2.2.16 kernel too.

Thanks to all,

M.E.
