Comment 33 for bug 292159

The two workarounds together works for me when running in live mode, i.e.

1) kernel updates work
2) running the latest kernel works

Including the second workaround, i.e. replacing
/cdrom/casper/initrd.gz and vmlinuz with the updated ones
though made a following test installation on harddisk unbootable.

The message I got was:
Starting up ...
[9.112117] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

This was due to that initrd.img was missing in
- /boot folder
- /boot/grub/menu.lst

Strange, but adding the initrd.img to both those places made the test installation boot up.

However, the pointer didn't respond to mouse movements and the network didn't connect, i.e. got stuck in trying to connect to the network. So I assume there is something still missing to be able to use an updated LiveUSB for new installations.

Before copying the updated initrd.gz and vmlinuz to /cdrom/casper installations worked. Furthermore, I also tried to copy the missing abi, config, System.map and vmcoreinfo files from the USB to the test installation but that didn't change anything.
