Porter
Charming Chinook (latest release)
I just flashed my Porter with the latest Chinook release, baked with agl-demo agl-appfw-smack agl-devel agl-sota
After I installed all apps, I started up the radio app, selected 100.5, hit the play button, and got a kernel panic

The app also appeared to "crash" as the screen went blank (no UI, had to go home and start up radio app again)
Looking at journalctl at around that time, right after the kernel warning:

I started up the radio app again and went to the desired station, hit play, and it seems to work now, although the sound has a high pitched whine
