Kernel debugger in MP mode causes double fault

[Markus Partheymueller]

Hi folks,

has anyone tried to invoke the kernel debugger in a multiprocessor setup?
When I boot the demo scenario in qemu with qemu -smp 2 -cpu core2duo and
then hit Escape, the system crashes with a double fault. Without smp or
with -cpu qemu32 the problem doesn't occur. Can someone confirm this issue
or give a hint what could be wrong?

Cheers

Markus
