2.0.32 3C59X 0.47 Driver Problem

[Paul Black]

We are running kernel 2.0.32 on a machine which is used as a router and
is also used to run a squid proxy. We are experiencing a problem about 5
- 6 times per day where the box stops routing packets for a couple of
minutes. Here is the kernel message which we get when the routing
temporarily stops:

Dec  5 10:08:37 core kernel: eth2: Transmit error, Tx status register
90.
Dec  5 10:08:37 core kernel: eth2: transmit timed out, tx_status 00
status e000.
Dec  5 10:08:37 core kernel: eth2: Host error, FIFO diagnostic register
0400.
Dec  5 10:08:38 core kernel: eth2: transmit timed out, tx_status 00
status e000.
Dec  5 10:08:38 core kernel: eth2: Host error, FIFO diagnostic register
0400.
Dec  5 10:08:38 core kernel: eth2: Transmit error, Tx status register
c0.
Dec  5 10:08:39 core kernel: eth2: transmit timed out, tx_status 00
status 8000.
Dec  5 10:08:39 core kernel: eth2: transmit timed out, tx_status 00
status e000.
Dec  5 10:08:39 core kernel: eth2: Host error, FIFO diagnostic register
0400.
Dec  5 10:08:40 core kernel: eth2: transmit timed out, tx_status 00
status 8000.
Dec  5 10:08:42 core kernel: eth2: transmit timed out, tx_status 00
status e000.
Dec  5 10:08:42 core kernel: eth2: Host error, FIFO diagnostic register
0400.

We have seen this problem with the 0.46C and 0.47 3C59X drivers.
Ifconfig shows the following status, the problem only occurs on eth2,
this is not unexpected as this card is handling most of the traffic.
Any ideas on what might be going on and how to fix it would be
appreciated.

Thanks.   Paul
