i grepped the source and "wait_for_cmd_done" shows-up in the eepro100 driver, not the e100... so i guess you're using the eepro100 driver now - i'm not sure if the above ucode stuff would apply to that driver (it might, though)...

from /usr/src/linux-2.6.15.5/drivers/net/eepro100.c:

Code:

/* How to wait for the command unit to accept a command.
   Typically this takes 0 ticks. */
static inline unsigned char wait_for_cmd_done(struct net_device *dev,
                                                                                
                struct speedo_private *sp)
{
        int wait = 1000;
        void __iomem *cmd_ioaddr = sp->regs + SCBCmd;
        unsigned char r;

        do  {
                udelay(1);
                r = ioread8(cmd_ioaddr);
        } while(r && --wait >= 0);

        if (wait < 0)
                printk(KERN_ALERT "%s: wait_for_cmd_done timeout!\n", dev->name)
;
        return r;
}

hi, the ucode parameter was meant to be used with the linux 2.4 e100 kernel modules and I use a linux 2.6 kernel. That was what was written on the website. I tried to do modprobe e100 ucode=0, it didn't work I was prompt that ucode was not a valid parameter. I tried to use insmod, and it was saying that there was no ucode symbol.
I then opened the code myself (e100.c) and inside the code, there was instruction on how to get the same effect that ucode=0 by changing the value of certain constant inside the code, but I was still left with the same problem.
Well this is pretty tough one to fix.
It came to my mind that it could be a hardware problem, but nope, because it was working fine under windows.
Right now I am running with the vanilla linux kernel, but it does not fix anything. I guess there must be another process not really compatible with my hardware, or must I have a different type of ethernet card in my thinkpad t23 not fully supported by the linux driver.
It is very hard to say.
I had a thinkpad t21, I should have switched the ethernet card before selling it on ebay, maybe it would have worked with the thinkpad t21 ethernet card, since it uses a different serie of ethernet card.

Thank you so much for your suggestion, please there are still welcomed.
I will be trying to keep on figuring out what is wrong.

Thanks again

how'd it go man?? still now luck?? i was just browsing through the 2.6.16 git tree and saw that there's been a very recent patch included for some e100 issues... i don't know if this will do the trick for you cuz i haven't looked into it but perhaps it might, so i thought i'd give you a heads-up... here's the patch:

Hi Guys,
Sorry for not responding lately. I was still desperatly having problem with my ethernet.
I never found a way to fix. Nothing had worked for it. I only had to replace my ethernet card, after having to reinstall gentoo completely in my laptop. Imagine. Gentoo itself, kde, and all the the software that I had and backups. It was so time consuming for nothing.
The only think that I can say is that, my ethernet card is not supported by linux. I bought another one ebay, using this time the mini PCI and everything is working very good.
Finally a working connection !!!

I am still learning to write drivers for linux, hopefully one day I will be able to fix drivers myself and write better drivers for linux.
