This works for me with QEMU 1.1 and GDB 7.4: gdb successfully stops at
the start_kernel breakpoint. So I'm going to close it as 'fix released'
on the assumption that we fixed the bug at some point between QEMU 0.12
and 1.1...

Title:
GDBStub Bug: Can't stop at start_kernel when debugging linux kernel
Status in QEMU:
Fix Released
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,
