[Qemu-devel] [Bug 1158912] Re: QEMU Version 1.4.0 - SLIRP hangs VM

[Kenneth Salerno]

Sorry for the confusion, I was impatient for the first bisect run to
complete - this time I figured out how to automate the testing portion
of the git bisect run script so I could walk away and let it run until
full completion.

Here is the result:

acbb090b2400f627a801074c4e3e006c7501bb26 is the first bad commit
commit acbb090b2400f627a801074c4e3e006c7501bb26

    prep: Include devices for ppc64 as well
    
    Allows running qemu-system-ppc64 -M prep for consistency.
