For debug I also like to add

--enable-debug-tcg --disable-strip

I usually add -s -S to the qemu command line and then:

gdb
symbol-file /<path to vmlinux>/vmlinux
target remote localhost:1234
info registers
continue
C-c
bt
info registers

Unfortunately setting breakpoints also doesn't work for me.
