Description of problem:
I installed RH 7.3 on an IBM Thinkpad T23. The install went w/o problems and
all the hardware was detected automatically. The network card is an Intel
82801CAM (ICH3) Chipset Ethernet controller (as returned from /proc/pci). The
eepro100 module was aliased in my modules.conf for this controller, but network
transfers hang when using this. Switching to the e100 module eliminated the
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. use the eepro100 module with the integrated ethernet
2. transfer some data using scp
3. transfer will hang
Actual Results: The network connection hangs
Expected Results: Data should be transferred uninterupted
The e100 driver eliminates all problems.
I can add that the installer (netboot.img) also hangs - if and only if I connect to a 10 Mbit/s hub (half duplex).
When I added a 10/100 MBit/s switch (full duplex) as a buffer between the PC and the hub, the installer ran fine.
On Windows 2000, the network card is listed as "Intel PRO/100VE" PCI bus 2 device 8 function 0
If is matters, I used DHCP settings, HTTP download from mirrors.sunsite.dk directory /redhat/7.3/en/os/i386 via a 2Mbit/512kbit ADSL line.
A new guy on the task? Ok, fine:
I've just upgraded to Redhat 9 using FTP install from ftp.sunet.se and the
boot.img and the driver disk.
The installer didn't recognize my NIC but I was allowed a list to pick from. I
used the Intel e100 driver and it works fine. In other words, I didn't test any
I still have the IBM T23 laptop and I can test any changes, you may want to
check on the actual hardware.
As e100 (not eepro100) appears to work, closing. We are deprecating
eepro100 in favor of e100.
