fpudna: fpcurthread == curthread XXXX times

[Jeroen van der Ham]

Hello,

I've been trying to compile a kernel for my FreeBSD9 XEN guest system using the provided XENHVM config. I found that that configuration works fine, unless you use a specific make.conf file.
When I used that make.conf file, booting from that kernel it spams the console with consecutive messages of: "fpudna: fpcurthread == curthread XXXX times"

The make.conf file that I used is an adapted version of /usr/share/examples/etc/make.conf:

% diff /etc/make.conf /usr/share/examples/etc/make.conf

Does anyone know what might cause this problem, and why it would not be caught earlier?
