Summary: 2.6.7 Linux Kernel Crash While Detecting PCI Devices
Please CC me on any replies.
Hi, I am responsible for maintaining a pre-boot Linux environment, for
which we use a 2.6.7 linux kernel, booted with the freeloader boot
loader. Our environment works well on most systems, but on this
particular model of laptop the kernel crashes before I get a shell
prompt. From the stack trace, it appears to be crashing during the PCI
device detection. The root filesystem is loaded into a ramdisk. The
crash doesn't always reproduce, and I'm not sure what changes that it
does or does not reproduce. But I see the crash on more than 50% of the
reboots.
Oops output from ksymoops:
Unable to handle kernel NULL pointer dereference at virtual address

the TI PCI1410 Carbus COntroller) allows me to extract the following

Hmmm... Not sure if Jonathan's problem is the same that I am having. But
I seem to have fixed my problem by compiling ACPI support into the
kernel. I still don't know why it was crashing, but I don't really know
how to go about figuring it out either. So since the crash doesn't
appear anymore I will likely not pursue this any longer.
