F18 Kernel panic with kernel 3.7

[expectATIon]

My system crashes randomly (I get a text console with a load of text). Some of the text refers to kernel panic. I am using kernel 3.7.2-201.fc18.x86_64. This has never happened to me before & I've been using Fedora since F15. I am using the Radeon driver and also have kmod-wl installed if this info is of any help

You might want to look for (strange) output in your dmesg and investigate lines that could indicate that something is wrong.

That's what I did when I had crashes in 3.6 and it turned out that the radeon driver and my system do not like the move to PCI-E 2.0 (so now I boot with "radeon.pcie_gen2=0" and it works fine since).
But this probably has nothing to do with your situation.

Thanks for the advice Dutchy.

I have also installed kdump and crash so I hope to be able to get some info using this tool

when I run:

sudo crash /var/crash/127.0.0.1-2013.01.17-13:18:08/vmcore /usr/lib/debug/lib/modules/`uname -r`/vmlinux

I get the following:

It seems swapper/3 is the offending command. Any ideas please?

If I run backtrace using the crash command bt I get:

I tihink braodcom-wl is causing my problem as I only get kernel panic with the wirless module loaded

Hi I am now on kernel 3.8.1-201.fc18.x86_64 and am still getting kernel panic with broadcom-wl

I have emailed linux-wlan-client-support-list@broadcom.com a couple of times with details of this bug but got no reply. Anybody got any information on it?
