--- Comment #2 from rkoberman at gmail.com ---
I have now tracked the crash to r361350, "Provide separate accounting for
user-wired pages." Revert this commit and everything works. With this commit,
the system crashes when I start my Windows7 VM. All backtraces are essentially
identical to the one in the initial report.

A bit more detail on the trigger. If the VM is in a "Saved" state, the crash
happens immediately after the image is loaded and started. If the VM is
"Powered off", the system boots up until it does its second window resize. The
initial window is the console window at 640x480. As soon as the system boot
starts, it resizes to 800x600 for the splash screen and the animated Wind7
logo. After a few seconds, it expands to the size I have set for the running
system, about 1480x816. At that time, the system panics.

Any ideas?Much as I hate to admit it, I do need my Windows system regularly.
