Question Upgrade FC3 to 2.6.14 results in kernel panic


Hi

I'm trying to update the kernel on my FC3 install from 2.6.12-1.1372 to 2.6.14.2

I'm using the vanilla 2.6.14.2 from kernel.org and did the following steps in making it...

Code:
make mrproper
make oldconfig (set everything that I could to module)
make all
make modules_install
make install
This created my initrd file and updated the grub conf file and all was looking good...

My system uses lvm and has the following in its grub.conf file...
Code:
title Fedora Core (2.6.14.2)
root (hd0,0)
kernel /vmlinuz-2.6.14.2 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.14.2.img
It is exactly the same (apart from file names) as the entry for the kernel that works.

I then rebooted and got a kernel panic with the following output...

Code:
Booting 'Fedora Core (2.6.14.2)'

root(hd0,0)
  FileSystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.14.2 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
    [Linux-bzImage, setup=0x1e00, size=0x19d9ac]
initrd /initrd-2.6.14.2.img
    [Linux-initrd @ 0x1def5000, 0x10d3a0 bytes]

Uncompressing Linux... Ok, booting the kernel
PCI: Cannot allocate resource region 4 of device 0000:00:1d.0
PCI: Cannot allocate resource region 4 of device 0000:00:1d.1

pnp: Unable to assign resources to device 00:08
RedHat nash version 4.1.18.1 starting
    Reading all physical volumes. This may take a while...

switchroot: mount failed: 22
umount /initrd/dev failed: 2
Kernel panic - not syncing. Attempting to kill init!
So vgscan cannot find my LVM partitions, the 2 "PCI:" lines are not normally there but lspci gives...
Code:
...
00:1d.0 USB Controller: Intel Corp. 6300ESB USB Universal Host Controller (rev 02)
00:1d.1 USB Controller: Intel Corp. 6300ESB USB Universal Host Controller (rev 02)
...
So I doubt the PCI messages have anything to do with it being unable to find the lvm partitions.

I've unpacked the initrd's and they have exactly the same files in their with the only differences between the files being for the modules (which is not at all surprising). So the initrd (seems to) contain the drivers for my scsi controller.

Does anyone have any ideas what could be wrong?
Any ideas where to look next?
Any way of getting more output before the Kernel panic.

Thanks for your help in advance

OK I've managed to get more debug output... if I edit the grub line and remove the "quiet" it prints all the dmesg output... unfortunately it all scrolls past to quickly to read it and Ctrl-S doesn't pause the output...

Can't see any useful error messages in there... any ideas how to slow the output down?

Never build the chipset drivers and filesystem drivers as modules!
The rest is ok to build as modules, like hotplug acpi usb sound nic
