Question Dell Inspiron 7500, 3com 3CCFE575CT, RH 6.1, DHCP Problems 

Forum: 3Com PCMCIA Ethernet Adapter Issues
Date: 2000, Mar 07
From: Dave Aiello dave_aiello

I am new to Linux, although I have a fair amount of end user experience with Solaris. In order to really understand Linux, I decided I would stop using Solaris and NT wherever possible, and work as much as possible with Linux. I decided that all I wanted to do, initially, was become very good at using Linux and operating it at a System Administration level. Note that I did not say that I wanted to install Linux or troubleshoot an installation.

So, I decided to buy a Dell Inspiron 7500 with RedHat installed in the factory. As you will see, I was surprised to find that the RH certified configuration did not "just work" out of the box.

In the initial configuration I set, I was unable to shutdown the laptop. When the shutdown process reached the point where it tried to shutdown the eth0 interface, it appeared to hang. I have also found that my NIC did not wake up properly after the machine was suspended. The symptoms are that the 3com network dongle light for 100 base T operations does not re-light, and subsequent attempts to use Netscape result in an error. I can't remember, but I think it was "no path to host" or something like that.

The initial configuration had DHCP enabled. It worked as long as you didn't try to shutdown or put the laptop to sleep.

I spent some time on Saturday and Sunday reading the PCMCIA project information here, and one of the hints given was to turn off DHCP and see if some or all of the problems resolve themselves. I did this, and put in an IP address that is free on my network. This had the effect of resolving my shutdown problem, but it did not resolve the suspend problem.

In addition, and I think this is interesting, before the change the machine would beep twice during the boot process. This was at the time that the inserted PCMCIA cards were identified. After the change, there is only one beep during the boot process, but there are an additional three beeps early on in the user session. It seems like the network is not being initialized during the boot process, although the only thing I am going on to make this judgement is the fact that off LAN pings did not go through for about 40 seconds after I logged in on one occasion after I reconfigured to turn off DHCP.

This is an edited version of the /var/log/messages file from the time I booted up this morning. Note that I have the clock on this system set to GMT.

I'd appreciate any help that fellow users and more experienced project members can provide.
