Title:
  GDBStub Bug: Can't stop at start_kernel when debugging linux kernel

Status in QEMU:
  New

Bug description:
  version: qemu-0.12.3
  my environment: arm-linux-gdb + qemu-system-arm + arm926 linux kernel
  my operation: 
  qemu-system-arm -kernel zImage -initrd cramfs.arm.rootfs -s -S
  arm-linux-gdb vmlinux
  >target remote TCP::1234
  >b start_kernel
  >c

  then qemu start and free run, not stop.
  when I pause gdb, qemu stop at rest_init() called by start_kernel()

  But if I use qemu-0.11.1 instead of 0.12.3, stopping at start_kernel
  is all right, and debug action seems allright too,
