Just finished a fresh install of FC9 and when I initial rebooted I got a kernel panic due to my pcmcia wifi card. Rebooted again without the card and it booted fine. Tried to plug the card in when the gui was up and complete freeze. Is this a udev issue? I sure would like to have wireless.

Have you done a "yum update" yet? Perhaps something in the updates will get your card working.

Perhaps that will work I'm hoping. The error at boot says EIP error FATAL. I tried tinkering with the udev rules by commenting some stuff out but I still got the error after that.

i remember a similar problem in 2007 which was actually a kernel bug which happened whenever a pcmcia networking device was inserted; either at boot-up or post boot-up. Someone suggested downgrading udev at the time.. not sure if that would work this time.

Not next to the lappy right now but the kernel would have been with whatever came on the install dvd media. I can't recall at the moment what version it is. Some does anyone think they know where to start if it's not fixed by doing the updates. Modprobe, udev, pcmciautils, etc.

After you get updates, state where it panics? Before the daemons are started or when networking comes up?

It would be nice to know the make, model and hardware id of the device (lspci, etc), assuming you can get to single user mode.

Also check the Fedora 9 common problems, including KernelCommonProblems.

That's the start...

Well after an update same problem. I can't get to any info regarding lspci or the such. The thing is I have used this card with previous versions of Fedora up to 8 and never had a problem with it locking up. The card is an old Microsoft card. I'm starting to think the card is bad, but I previously had xp on it less than a week ago with no problems. So I'm not sure.

At every boot is a log file generated? If so when it locks the way it does will the info be recorded somewhere where I can get to? I would like to boot with out the card and examine that file for maybe some clues.

I'd boot into single user mode without the card, then plug it in.

If you are lucky, /var/log/messages will get something and still have it on the next boot.

I'm pretty sure the kernel developers install a debugging version of the kernel, and hook up a serial port, then add a kernel parameter to redirect the console to the serial port while they debug these kind of issues.

There are a few details about debugging kernels in the "KernelCommonProblems" on the fedoraproject.org web site.
