[panic] currnet(r238089) cause panic when using '/usr/sbin/amd'

[YAMAMOTO Shigeru]

Hi all,

I try to update newest current (r238089).
I have kernel panic when using '/usr/sbin/amd'.

This kernel panic is not caused without using '/usr/sbin/amd'.
In old current (r236371), I have no problem with using '/usr/sbin/amd'.

Currently, I don't know how to fix it.
So I can only report this proble to ML.

Thanks,


How to repeat:
1) "svn checkout" r238089 source code
2) "make buildworld" and "make buildkernel"
3) "make installworld" and "make installkernel"
4) reboot
5) boot "GENERIC" kernel
6) run amd, "/etc/rc.d/amd onestart"
