tg3 Errors?

[Hart Larry]

Well, shortly after updating a speakup colonel, I began getting these errors, 
which would come in groups.  During some times, seemingly my DSL grinds to a 
halt, although I am still ssh in to my shell-account, just can't type any 
commands.  Today while also running bitorrent-console  I am receiving more of 
these errors, which look like this
  tg3: eth0: transmit timed out, resetting
tg3: tg3_stop_block timed out, ofs=1400 enable_bit=2
tg3: tg3_stop_block timed out, ofs=c00 enable_bit=2

Would upgrading to FC6 help, otherwise, please, how can I solve this?
I have speakup with a dec-talk-usb on fc5
Thanks in advance
