[Qemu-devel] linux 2.6.21 tickless kernel problem

[zjs]

Hi, all

Host os:linux(kernel 2.6.21 with CONFIG_NO_HZ=y to enable tickless feature)
Guest os:RTEMS or Haiku etc.
QEMU:0.9.0, no kvm and no kqemu

The Guest oses halted. RTEMS gave a message:"problem #2 in offset 
computation in Calibrate_loop_1ms in file libbsp/i386/pc386/timer/timer.c".

I recompiled my host os kernel with CONFIG_NO_HZ=n, then everything was 
ok. Is this a bug of qemu or of kernel of RTEMS and haiku?

Best Wishes,
