I get this stacktrace when I try to boot from a Kernel as of today (svn: 

My setup is a 7.1 install where I'd like to upgrade to current.
The kernel is built cross, amd64 -> sparc64:
make -j4 buildkernel TARGET_ARCH=sparc64 KERNCONF=GENERIC

The target machine itself is a u60, details below.

Does anyone have a pointer to help me, would be great!


Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel]...
jumping to kernel entry at 0xc0080000.
