Hi,

We're having this problem for long time (from the old 4.0-CURRENT days), but Mr. SUMITANI discovered a bug and fixed it. The problem was that we got worng gdt pointer for the current cpu, then panic... The followings is a patch to fix the problem. Thanks a lot, SUMITANI-san! Please test this and I'll commit & MFC this if we have no problem with this fix. I love to have APM enabled SMP system with 4.1-RELEASE.
