Description Paolo Prandini 2003-11-09 18:56:42 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1)

Description of problem:
I have installed FC-1 on Toshiba TECRA 8200.
I have an ADSL Switch configured as a DHCP server,
with two PC connected : a custom made with RH9 and this TECRA 8200.
I have checked cables (swapping them) to exclude hardware problems
and configurations. All appear to be good.
The Network module loaded is e100. 
this is the output from ifconfig eth0
[root@localhost Add-on]# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:00:39:A9:F4:2E
          inet addr:  Bcast:

How reproducible:
Couldn't Reproduce

Steps to Reproduce:
1. Browse the Internet
2. at some point the connection is lost
3. do a /etc/init.d/network stop; /etc/init.d/network start
4. at this point the connection is up again

Actual Results:  Connection works again for a random period of time.

Expected Results:  No connection loss.

Additional info:

You can speed the connection loss (reducing the random time between
two failures) by wget to some site or running yum in the background.

RH9 was running fine on this same computer.

Comment 2 Paolo Prandini 2003-11-09 19:16:35 UTC
Done some other testing, found a way to reproduce.
While browsing (ephipany or mozilla) simply initiate a big download,
like the JAVA 1.4.2_02 JRE or SDK and after 28-30 sec you the
connections hangs until you restart network interface.
Already tested 10 times, connection hangs always in 28-30 sec.
It seems something in the NIC module or Network isn't able to sustain
an high data rate (ADSL 640Kb) for more than 30 secs.
With pages or downloads that have a duration of some secs this does
not seem to happen or happes randomly.

- Hope it helps

Comment 3 Paolo Prandini 2003-11-10 13:38:39 UTC
I have done some other testing.
Mozilla or Epiphany doen't matter, network hangs again in the some
I have recompiled the kernel using 2.4.22 from kernel.org,
with all the necessary modules. The problem still persists.
The last kernel that I was running on this machine w/o problems was a
RH9 stock Kernel 2.4.20-20.9.i686. 
On the same machine I have Windows 2000 as a boot option. Tried out
Windows 2000 to download the same file and I succeded. This takes all
the hardware problems out of the game. 

- Hope it helps

PS : If any suggestions, please do. I would not go back to RH9. I like
Fedora.... :-)

Comment 4 Jeff Garzik 2004-01-12 19:02:46 UTC
Does 'dmesg' produce any error messages related to e100?

Comment 5 Paolo Prandini 2004-01-19 19:29:56 UTC
No. 'dmesg' looks fine.

Comment 6 Brent Deterding 2004-01-29 17:56:47 UTC
I am also having this problem - although mine is with stock RH9.
Although mine doesn't seem too dependent on load - it will stop
working after a short period of time with zero network traffic.

I have a brand new Toshiba Satellite Pro 6100
I am using a freshly compiled e100 module from Intel (2.3.33)

Comment 7 Brent Deterding 2004-01-30 06:26:26 UTC
I apologize - although the problem persisted after unloading the stock
e100 module and reloading the new one a reboot seemed to fix the problem?

Comment 8 Paolo Prandini 2004-02-17 20:28:36 UTC

Yes a reboot gives me a goood fresh start, until I do not ftp
something ....
