[Bug 65836] Problem with Toshiba L100 and RTL8139

[windwalker]

Public bug reported:

A month ago I installed Ubuntu 6.06 on my Toshiba L100.This is my first linux install. Evertything is just fine except for the ethernet RTL8139. When I copy large files the network adapter just hungs and I have no network connectivity at all. The same things happens even with low traffic activity after 3-4 hours. I installed the latest official updates via update manager. Kernel is 2.6.15.-27. I read all posts and tried:
1. #ifdown eth0
    #ifup eth0
    The interface will come back only after restart
2. I noticed two drivers installed 8139too and 8139cp. My ethernet controller will work only with 8139too, so I removed 8139cp.Still the same result
   #ifdown eth0
   #rmmod 8139cp
   #rmmod 8139too
   #modprobe 8139too
   #ifup eth0
3. Tried turning off acpi by adding acpi=off or pci=noacpi. I cannot boot at all with this two options. Then tried noacpi and was able to boot to gnome, but the problem was there.

4. I installed kernel 2.6.18 and installed 8139  in kernel 
(not as module). This resulted in little better performace. Now I can copy in 70% of the cases a 500MB file.

5. Tried driver from Knoppix, but versions were different when I checked
dmesg. BTW with Knoppix 4.02 and 5.01 it works perfectly.

I see other people have the same problem without resolution:
