Hi folks, we're working on a drmkms update. I'm testing it on a Dell XPS 9550. It's a laptop with a Skylake CPU. It has a power button. The power button powers off, not reboot. This means the dmesg buffer gets wiped. No serial console as far as I know.
Now it reaches a point where the screen changes, but my DDB_COMMANDENTER containing "reboot" won't do the expected thing. It's possible it's hanging. I can't seem to blindly enter ddb. Any suggestions to make debugging less painful? Something like arm a watchdog to panic after some time. I'm gonna experiment with sprinkling panic("XXX"); and see if this works out.
