Description of problem:
Networking was fine with RH 7.1 on the same machine. After doing a clean 
install of RH 7.2 I immediately began seeing network failures. I did 
another clean reinstall producing the same results. The net will seem OK 
until I try to download something using (lynx, netscape, ftp, etc.) It 
seems that the additional load of the download will cause a hang/stall 
never to recover. After failure I will Ctl<C> out of the program and do a 
ifdown/ifup. This will bring the net back up. It will fail consistantly 
any time I try to download. I am using a static IP connecting to a hub 
connecting to a LinkSys router. I have tried reconfiguring several times 
with different IP's with the same result.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Try to download a file using Netscape, Lynx, FTP, etc..
2.The download process will stall/hang
3.Ctl<C> out of the program.
4.Do ifdown/ifup.
5.Repeat the process to cause another failure. 

Actual Results:  The network will stall/hang/fail.

Expected Results:  A succesful file download

Additional info:

1)I have a Toshiba 2805-S402 Satellite with a Pentium 850 and 256M RAM.
2)The only error messages I have seen (in messages) is:
kernel: NETDEV WATCHDOG: eth0: transmit times out
kernel: eth0: Transmit timed out: status 0050 0c80 at 504/532 command

The network also crashes with normal browser (surfing) usage.

Comment 2 Arjan van de Ven 2001-12-13 09:00:01 UTC
Any idea what network card this is ?

Comment 3 Need Real Name 2001-12-13 15:47:18 UTC
Yes, it is an Intel Pro/100 VE.

Comment 4 Arjan van de Ven 2001-12-13 15:52:01 UTC
Ok then I have recently made a kernel with a fix for eepro100 crashes:
I'd be very interested to know if this kernel fixes your problem too....

Comment 5 Need Real Name 2001-12-13 19:00:45 UTC
I installed your fixed kernel (2.4.9-17.6) and have been testing it for several 
minutes. The results are the same. When I download (or browse) the network

Anything else I can do to aid in debug? Do you want me to attach log files, 
config. info., etc..

Comment 7 Arjan van de Ven 2001-12-19 15:28:32 UTC
You can try to use the e100 module instead (by replacing "eepro100" with "e100"
in  the /etc/modules.conf file)... it has a few more workarounds for hardware

Comment 8 Need Real Name 2001-12-19 16:44:10 UTC
As per your advice I installed the e100 module. I have been testing it for a 
few minutes and it seems to be working. I have downloaded some large files that 
always produced failure with the eepro100 module. What is the downside to using 
the e100 module versus the eepro100? (performance?). I am using it in 
conjunction with your (2.4.9-17.6) kernel. Is this OK? Will it be stable? Will 
there be a fix to the eepro100 module in the near future? Thanks for the help...

Comment 9 Arjan van de Ven 2001-12-19 18:19:57 UTC
the quality of the e100 driver implementation is rather poor; however in normal
cases you won't notice it; in corner cases (such as network error conditions)
the driver can freeze your system for several seconds though... however that
still beats not working at all ;(

Comment 10 Need Real Name 2001-12-19 19:42:12 UTC
Will there be a fix for the eepro100 driver in the near future?

Comment 11 Arjan van de Ven 2002-01-04 11:09:58 UTC
We're doing what we can, but Intel is "not exactly helpful" with this.

Comment 13 Gordon Messmer 2002-03-04 18:23:43 UTC
This bug may not be a duplicate of #56058.  The kernel messages are different. 
This sounds like the APIC problem (maybe) that seems to affect a lot of ne2k-pci
users (I just got bit by this).

There's a patch which may fix the problem here:

It's speculation on my part, but I thought I'd suggest it.  I'm testing the
latest errata kernel on my machine now, after the APIC problem left it down all
