IN A NUTSHELL
The kernel in the 2015.08.01 ISO panics at boot for me under VirtualBox with multiple processors.
By fluke, I found that if I change the VM back to 1 processor, it boots fine.
LONGER STORY:
I just updated (via pacman -Syu) an existing Arch system I had running under VirtualBox.
(It had been a while since last update. My bad...)
On reboot I got a kernel panic.
Decided to throw it in rebuild my VM from scratch because I wanted to change a few things anyway.
But with similar VM config (I change a few settings from defaults) in a brand new VM I got the SAME KERNEL PANIC FROM THE LATEST LIVE BOOT CD.
Which leant me towards some experimentation to find out what might be causing it. After changing a few things, I found setting the number of virtual CPUs to 1 allowed it to boot. Any other number results in the panic.
I don't know how to get the full trace of a boot panic sorry.
But a part that looks interesting includes::
EIP: [<c13516d3>] free_cache_attributes+0x83/0xd0 SS:ESP 0068:f50b3ea0
The host is Linux Mint on an AMD CPU, running VirtualBox 4.3.28.
I have the new VM 'on-ice' if anyone would like to get me to take a closer look.
For now I will run the VM I need on 1 CPU. But that might get annoying fairly quickly.

I tried to install a completely different Arch derivative (Antergos), and got the same panic during installation.
I've been trying 32-bit versions, as my memory requirements for the VM are not high. (Sorry, forgot to mention that earlier)
I tried a 64-bit version and that installs fine.
Perhaps 32-bit OS's are effectively going obsolete and my luck will be better with 64-bit?
