eth0 problems all of a sudden

[petong <petong@jah.net>]

Hi list,

I am running unstable and yesterday I was attempting to shut down from kdm 
and my machine froze. Upon rebooting, I had problems with eth0. This is what 
I used to get on boot:

PCI: Found IRQ 11 for device 00:0a.0 
3c59x.c:LK1.1.15 6 June 2001 Donald Becker and others. 
http://www.scyld.com/network/vortex.html 
See Documentation/networking/vortex.txt 
00:0a.0: 3Com PCI 3c905B Cyclone 100baseTx at 0x6c00, 00:10:4b:12:1c:6a, IRQ 
11 
product code 4e4b rev 00.9 date 10-29-98 
8K byte-wide RAM 5:3 Rx:Tx split, autoselect/Autonegotiate interface. 
MII transceiver found at address 24, status 786d. 
Enabling bus-master transmits and whole-frame receives. 
00:0a.0: scatter/gather enabled. h/w checksums enabled 

I now get this:
PCI: Enabling device 00:0a.0 (0000 -> 0003) 
PCI: Found IRQ 11 for device 00:0a.0 
3c59x.c:LK1.1.15 6 June 2001 Donald Becker and others.

1024K word-wide RAM 3:5 Rx:Tx split, autoselect/<invalid transceiver> 
interface. 
Enabling bus-master transmits and early receives. 

I then get the error 
NETDEV WATCHDOG: eth0: transmit timed out

can anyone shed some light for me on this problem?

TIA
