This time cc'ing the people who signed-off-by the buggy commit. Before commit 02c4bdf1d2ca signal handling in qemu-system-sh4 with serial console on stdin/stdout worked properly, as in ctrl-c would kill the shell, not the emulator. After that commit, ctrl-c kills the emulator, not the shell. You can test this by grabbing the tarball in the first line above, and runnign the run-emulator.sh script, which is just: qemu-system-sh4 -M r2d -nographic -no-reboot -kernel zImage -hda hda.sqf -append "root=/dev/sda rw init=/sbin/init.sh panic=1 PATH=/bin:/sbin console=ttySC1 noiotrap HOST=sh4" -monitor null -serial null -serial stdio Again, this worked before the above commit, and has been consistently broken since that commit.
