Ok, I posted in the wireless forum and have been working with 2Gnu (who has been very informative) but unfortunately we have not solved my problem.

I have a compaq presario 2140 laptop and I downloaded and installed Fedora 5. Everything seems to work fine except my wireless pcmcia card and my touchpad is pretty quirky. The touchpad aside, I REALLY need to figure out my wireless card. 2Gnu has established that I have an original Orinoco Gold Classic card with the hermes/Orinoco_cs chipset/driver:
http://www.linuxquestions.org/questi...02#post2474902. This card/chipset is supposedly nearly plug and play with Linux?

The problem: I think I have the right drivers/modules loaded but the system locks and/or refuses to work with this wireless card. If I plug the card in at boot-time the OS hangs right after the second line after it says “push I for interactive startup” and udev starts loading. If I plug the card in after the OS is loaded and then I type pccardctl insert the computer will again freeze. The only way to fix at that point is to eject the card are do a hard reboot.

2Gnu told me it could be a conflict with the bios/acpi settings. I am not real familiar with acpi or apm settings and even less so in Linux. After being told that, and doing some research on the subject, this sounds like a real possibility. Unfortunately I need step by step advice and how to deal with it.

I’ve included various, hopefully informative output of a few pertinent commands:

I don't think I changed the boot file properly; I wasn't sure exactly where to insert the pc=noacpi option. My line looks different then the insertion 2Gnu showed in his example: kernel /boot/vmlinuz-2.6.10-5-386 root=/dev/hda6 ro pci=noacpi. I was trying to disable ACPI services (I think) to see if that affected the lockup situation. Here is a snippet of the /boot/grub/menu.lst file that he told me to modify.

# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

I would like to thank 2Gnu for all the help. I am hoping someone else might see this, have had a similar problem, and know exactly what is going on.

Hmm..........

I see no pcmcia_core and/or yenta_socket loaded from your lsmod output

What does cat /proc/interrupts show??

This does not look good, both your pcmcia interface and video card are sharing the same IRQ; 10: 17996 XT-PIC yenta, radeon@pci:0000:01:05.0

Does the earlier kernel (2.6.15-1.2054_FC5) work with the wireless/pcmcia devices, can you use the wireless pcmcia card in other words with this kernel or do you have the same IRQ issue??

I also noticed no IRQ's above 15 are listed, perhaps you might want to change that and enable/use acpi??


Many years ago now I learned how to build my own kernels because of issues with the exact same pcmica controller and wireless card as you with the kernels as supplied by Red Hat back then (RHL-6.2 and higher). Maybe it is time you learned how to build your own kernel; http://www.digitalhermit.com/linux/K...ild-HOWTO.html

Building a new kernel for Red Hat / Fedora differs a little bit from the guide, the steps in order are;

make mrproper (or make clean after the first time)
make menuconfig
make
make modules_install
make install

The 'make menuconfig' step is the most important one and two things to note. First if your building a new kernel from the kernel.org source then the configuration file from Red Hat / Fedora will not work because the changes they make to their supplied kernel sources. And take the time to make sure you configure the kernel for not only your hardware but also some needed things like netfilters section. It may take a number of attempts to build your first working kernel but it is worth the effort.

First, so your saying I did successfully kill acpi at bootup with that noacpi line I added in the bootup script? I didn't think it was in the right spot.

Second, the "yenta" is specific to my pcmcia controller on the motherboard and since both it and the graphics interface are sharing the same IRQ, this is most definitely the issue with the computer freezing when the card is inserted?

Third, the reason IRQ's above 15 are not listed is because of the "noacpi" line I added to bootup? I need to remove this to make above 15 available again?

In conclusion, to fix my problem I need to resolve the conflict and the only way to do this is by recompiling the kernel (which for me, is going to be a great challenge)?

Just as a note: I did try to boot to ubuntu desktop with a live cd, and it froze in the same manner with the card insert. It too, wouldn't boot with the card inserted at bootup. I believe ubuntu is based on the Debian distro but I have no idea how this relates or not to the latest kernel.
