Description of problem:


After the initial kernel compress the rawhide DVD gets to some lines starting with "ACPI" before crashing with a kernel dump and the final line:

Kernel - panic : not syncing : Fatal exception in interrupt


How reproducible:

9 out of 10 attempts so far

Steps to Reproduce:
1. Start virtual box on a FC9 installation
2. Create a new VM
3. Mount the rawhide iso as a cd\dvd and start the VM
4. Elect to "install or upgrade an existing system"
5. Observe the brief pause at the "SMP Alternatives - *" line
6. Get to some lines refering to ACPI and then observe the kernel crash
  
Actual results:

Kernel crashes on start up, forcing hard reset of the machine

Expected results:

Kernel uncompresses and proceeds to the anaconda graphical installer

Additional info:

Unsure whether this is related to working under VirtualBox or whether the crash can be observed under native hardware.
