I've made reboot both sw03 and sw04 several times.

According to the iStack whitepaper, you have made a few errors.  I have attached it because I don't know where to find it on the website.

For starters, your switches should not have the same stack number, additionally, you may also need to connect a "stack port 1" to a "stack port 2" (right now, you have two "stack port 1" ports connected together)
