This recent patch may explain why the latest x86_64 developmental
snapshot crashes in a 32-bit version of VirtualBox 3.2.8. This was
covered in IRC, but the Sept 27th snapshot crashes very soon after the
kernel loads in the 32-bit version of VirtualBox. I confirmed this on
both OpenSolaris and Windows XP. Apparently it does not crash in a
64-bit version of Vista according to swildner.
It was suggested that I escape to the loader and set
hw.madt_probe_test=1 before booting the kernel. I did this, and I was
able to boot the snapshot. This is definitely a regression because I've
been running 64-bit DFly 2.6 release on a 32-bit VBox for months without
issue.
I imagine anyone with access to a 32-bit version of Vbox could reproduce
what I'm seeing easily.
