Too many carrier errors and too few RX packets problem

Hi!
I'm using a 3Com 3c905 Boomerang 100baseTx with Linux 2.2.14 but I'm
having the following problem, as reported by ifconfig:
eth1 Link encap:Ethernet HWaddr 00:60:08:59:2F:62
inet addr:192.168.192.64 Bcast:192.168.195.255
Mask:255.255.252.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:7326 errors:0 dropped:0 overruns:0 frame:0
TX packets:1317 errors:0 dropped:0 overruns:0 carrier:1317
collisions:0 txqueuelen:100
Interrupt:9 Base address:0xef00
I have a lot of RX packets but too few TX packets (No, I'm not ftping
other servers :), and the carrier error increases as much as I use the
network card (even in a simple telnet session). It's forced at 100/full
in the NIC and switch. I tried also using 10/half, 100/half and 10/full.
The cable is ok (I tested it with a cable tester) and the switch port
also. I even switched the cables and the switch port. Even changed the
switch (from a Cisco to a Bay), and the problems persists. I was using
kernel 2.2.10 and with 2.2.14 the problem persists.
I compiled the driver as module and tried some options at insmod. Here
is some output of "debug=6":

Is there anything wrong in these messages ?
I found also a "strange" message:
Mar 6 18:48:25 srv kernel: Receiving packet size 98 status 8062.
Mar 6 18:48:25 srv kernel: eth1: exiting interrupt, status e000.
Mar 6 18:48:25 srv kernel: pt, status e000.
Mar 6 18:48:25 srv kernel: eth1: Trying to send a packet, Tx index 141.
And these are the output when I was shutting down the interface and
unloading the module:
Mar 6 18:50:46 srv kernel: eth1: exiting interrupt, status e000.
Mar 6 18:50:46 srv kernel: eth1: vortex_close() status e000, Tx status
00.
Mar 6 18:50:46 srv kernel: eth1: vortex close stats: rx_nocopy 8
rx_copy 58588 tx_queued 58311 Rx pre-checksummed 0.
Any ideas ?
Thanks!
Sergio Salvi.
