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,
