Li Guanglei ??:

I don't have a x86_64 at hand. I tried __switch_to(scheduler.ctxswitch in src/tapset/schedule.stp) and it will cause kernel panic. I will take a further look at this and will open a bug for this if needed.

I tested again with 2.6.16.16 & 2.6.16-1.2211_FC6 on x86, _switch_to won't cause kernel panic any more. So I think this bug has been fixed in latest kernel.
