    Hi All,

    Just picked up a new mini tonight to use as an htpc. I did the collective updates when I first got the machine. It applied the updates, rebooted but didn't come back on. So I unplugged it and started it back up. It kernel panic'd when it came back up, and now I'm wondering what the problem might be.

    Here is the panic log:

    Any thoughts or ideas? Could it just be perhaps the EFI update?

    Thanks all!

    Yes, I experienced the same error on 2 brand new units after it applied the EFI update.

    Boot in 64-bit mode?

    I had that problem when I tried booting my i7 mini in 32-bit mode. Try pressing the 6 and 4 keys on your keyboard when booting up to force the Mac to use the 64-bit kernel. If it booted up fine, type "sudo systemsetup -setkernelbootarchitecture x86_64" in the terminal, enter your admin password, and it should boot fine in 64-bit mode. If it doesn't boot up when you press the six and four keys (it might take you a couple times to do this...), press command-r to boot to the recovery partition and try repairing the disk, etc... If it still won't boot, you might need to do a wipe and install.
