No, it's a sparc64 issue.
Another problem I ran into are the huge static table sizes
lockdep uses. They really need to be either made smaller or
dynamically allocated.
Sparc64 has hard limitations on kernel size (due to firmware
and bootloader issues) and I hit these limits if I am not
careful on SMP with lockdep enabled.
Andi Kleen and I discussed in a thread several weeks ago.
I believe Andi even came up with a suggested direction to
fix this.
